Who Can Use This Equipment
• This equipment must only be used by people suitably trained in the use of pipe and cable locators.
Work-site Safety
• Use your company’s or other applicable safety codes and rules when using this equipment.
• Unless having the required authorization, license, and appropriate training, do not connect to any pipe, cable, or conductor.
• The equipment should not come in contact with corrosive or hazardous chemicals, gases or dust.
•Do not directly connect this equipment to cables or pipes with a potential difference to ground greater than 25V AC.
Equipment Safety
•Do not open the enclosures (housings) of either the transmitter or receiver.
• Place the ground stake firmly in the ground before connecting the cable from the transmitter.
•Do not hold any uninsulated portion of the connection leads & clips when the transmitter is switched on.
Batteries and Environmental Safety
Vivax-Metrotech products use four types of batteries:
•Alkaline batteries
•Ni-MH (Nickel-Metal Hydride) batteries – rechargeable
•Lithium-Ion batteries – rechargeable
•Lithium-Metal batteries – (small non-rechargeable button cells for “clock” applications)
1. Alkaline Batteries (Non-Rechargeable)
• When replacing the alkaline batteries – use only the size and type specified – do not mix battery types (rechargeable and alkaline).
•Do not mix partially discharged and fully charged cells in the same battery pack – do not mix old with new.
•Never attempt to charge alkaline batteries.
2. Nickel-Metal Hydride Batteries (Rechargeable)
•When using rechargeable batteries, use only the correct charging device supplied or specified by the manufacturer. The battery pack or the battery charger will contain
circuitry to manage the charging process – other chargers (even if they have the same connector, polarity, voltage & current rating will not have the same control circuitry
and can cause damage to the product, overheating, and in extreme cases fire or harm to the individual.
•Do not assume that if the plug fits, it is the correct charger – a charger with the correct part number must be used – just because it is a Vivax-Metrotech charger and the
plug fits it does not mean it is the correct charger.
•Before using for the first time, charge rechargeable batteries for six hours. If the rechargeable batteries do not last as long as anticipated at any time, discharge fully and
then charge for six hours.
•Care should be taken when charging batteries – Never repeatedly recharge batteries (or turn the power off & on) without using the instrument. If used with an inverter in
a vehicle – charge the product, unplug the charger, and not charge again until the rechargeable batteries have been used for at least ten minutes. Failure to do this could
result in the overcharging of the battery, which will shorten the battery's life and could, in some circumstances, cause overheating or fire.
•If the product becomes hot during the charging process, immediately unplug the charger, and use the rechargeable batteries for at least ten minutes before recharging. If
this happens, the next time the unit is charged, return it to Vivax-Metrotech for replacement.
•Do not charge batteries for prolonged periods without using the locator for at least ten minutes. Charging for a prolonged period could overcharge the battery, reduce
battery life, and in extreme circumstances, cause damage to the locator and fire.
3. Lithium-Ion Batteries (Rechargeable)
•Lithium-Ion Batteries – some products use Lithium-Ion batteries – the requirements for marking and transportation are still developing. Please contact Vivax-Metrotech
before shipping products containing Lithium-Ion batteries or Lithium-Ion battery packs on their own for any “special instructions.”
4. Lithium-Metal Batteries (Non-Rechargeable)
•Commonly known as “button cells,” these are small – non-rechargeable batteries used to power internal “clocks” within some units (similar to computers). Generally, they
have a life of three to five years.
•Under no circumstances should any attempt be made to charge these batteries.
•Dispose of using your company’s work practice/environmental standards, the prevailing laws, or recognized best practice. Always dispose of batteries responsibly.
5. General Rules regarding Disposal of Batteries
•Never disassemble a battery or battery pack.
•Never dispose of in a fire or water.
•Dispose of batteries following your company’s work practice/environmental standards, the prevailing laws, or recognized best practice. Always dispose of batteries
responsibly.
6. Transportation of Lithium-Ion and Lithium-Metal Batteries
• The Lithium-Ion and Lithium-Metal batteries used in Vivax-Metrotech products meet the required safety standards and include the designated protection circuitry.
•Recent regulation changes require that when batteries with Lithium-Ion and Lithium-Metal batteries are transported, the packaging must include specied warning labels.
•Please contact Vivax-Metrotech Customer Service (USA 1-800-446-3392, International [phone] (USA Pacic Time Zone)) for more details.
•Regulations have also changed regarding the shipping of spare battery packs (battery packs that are not inside a product). There are limitations on the package's weight,
and the packaging must be marked with the appropriate warning labels.
•Please contact Vivax-Metrotech Customer Service (USA 1-800-446-3392, International [phone] (USA Pacic Time Zone)) for more details.
•Vivax-Metrotech vLoc Series 3 products using Lithium-Ion battery are classied as “not restricted.” They can be shipped normally by road/rail/sea & air (passenger & freight
aircraft) without restrictions.
IMPORTANT
Remember – Batteries contain dangerous chemicals – They can be affected by many things such as water ingress or heat – In some
circumstances, they can explode. They also can cause electric shocks!
General Safety & Care Information

Care of Equipment
• Use equipment only as directed in this User Handbook.
•Do not immerse any part of this equipment in water.
• Store in a dry place.
• Keep equipment in the case provided when not in use.
• If left for a prolonged period – remove alkaline batteries.
• Keep the unit clean and free of dust and dirt.
• Protect against excessive heat.
Care when Interpreting the Information provided by the Locator
•Like all locators – this instrument is locating and providing depth and current readings based on electromagnetic signals that radiate from the buried cable or pipe. In most
cases, these signals will enable the locator to pinpoint both position depth and current correctly.
•Beware – in some cases, other factors will distort the electromagnetic fields radiating from cables or pipes being located, resulting in incorrect information.
•Always locate responsibly and use information learned during your training to interpret the information provided by the locator.
•Do not provide information regarding cable or pipe depth to anyone unless authorized to do so by your company.
•Remember that depth measurements are to the center of the electromagnetic field or pipe – In the case of pipes, this may be significantly deeper than the top of the pipe.

2.2 Charging the Receiver Batteries
The RTK-Pro can be used with either alkaline batteries or an interchangeable rechargeable battery pack.
The central illuminated section within the battery icon indicates the amount of charge remaining.
• Blue center indicates alkaline batteries.
• Green center indicates rechargeable batteries.
• When batteries are low, the remaining charge section becomes red and will flash.
• Just before shutdown, the following symbol will be shown:
Rechargeable batteries are supplied with a mains charger. This charger is specific to the batteries used. Avoid using other
manufacturers’ chargers as these may damage the battery pack and result in overheating the battery pack.
To charge the rechargeable batteries, rst make sure the pack is inserted in the receiver battery compartment as charging is
done with the battery inside the receiver.
Connect the charger to the charging/accessory socket of the receiver. Connect the charger to the mains and switch it on. The
LED indicator on the charger will illuminate red until the batteries are fully charged, at which time the LED will change to green.
WARNING
Rechargeable batteries are supplied with a main or 12V DC charger. These are specific to the
batteries. Only use the charger that is appropriate for the batteries in the product. If in doubt, call
the Vivax-Metrotech customer service department at [phone]. Failure to use the appropriate
charger could damage the battery pack, locator and, in extreme cases, cause a re.
Avoid charging the unit in extreme temperature conditions. (i.e., below 0ºC and above 45ºC)
Although Vivax-Metrotech batteries include all the required safety-related features, immediately
discontinue the charger and battery pack's use if the battery pack becomes excessively warm. Return
both to where they were purchased for investigation.
Always ensure batteries have at least a partial charge if storing for long periods without use.
Dispose of all batteries following your company procedures and or Federal/State and local
regulations.
Never dismantle batteries, put them in a re, or get wet.

2.6.1 Warnings and Alerts Descriptions
ALERT Alert Description
Signal Overload - is usually caused by operating close to power transformers or being close to a transmitter in
Induction mode. Moving away from the interfering signal will cure the problem.
Shallow Cable - alerts indicate that the locator has detected a possibly less than 15cm (5.9-inch) deep cable.
Proceed with caution.
Swing Alert - indicates that the operator is swinging the locator excessively, resulting in misleading information.
When sweeping the locator across the direction of the line, try to keep it vertical; this will improve its accuracy.
Overhead Cable - alerts indicate that the source of the signal is mainly radiating from above. This alert is usually
caused by the signal traveling along overhead cables.
2.6.2 DFT (Discrete Fourier Transform)
DFT is a tool to assist in choosing a frequency to apply to the target conductor. The DFT feature will aid the user with nearby
interference that may a󰀨ect the locate quality.
*Note the DFT feature should not solely be used to determine which frequency to apply. ALWAYS
follow the appropriate safety requirements mandated by safety legislation, safety practice, or your
company’s safety procedures when applying a locate frequency to a conductor.
1. To perform a DFT assessment, verify any nearby transmitters are powered off to avoid additional signal frequency
disturbance.
2. Select your preferred frequencies from the frequency menu. These selected frequencies will be assessed in the next few
steps.
Frequency
128Hz
480Hz
491Hz
512Hz
577Hz
815Hz
982Hz

displayed. The frequency under test is shown on the top line.
Frequency: 8.19kHz
491Hz
512Hz
80 dB
74 dB
6. A numerical value ranging from 0dB to 140dB will be presented next to the frequency list, with 140dB being the least
possible interference detected and 0db with the largest amount of possible interference.
7. The results are ranked from the least interference possible at the top to the largest amount of most possible interference at
the bottom.
8. In this case, the higher the dB number (80dB), the less interference has been detected by the receiver.
Frequency: 491Hz

* Note - although frequency results appear to have less interference, it still does not make it the best
choice to locate certain utilities. These include but are not limited to a conductor, current output,
resistance, and signal bleed over adjacent utilities.
2.7 Setting up the vLoc3 RTK-Pro mapping functions
Introduction
This section describes the set-up and operation of the vLoc3 RTK-Pro in terms of the GNSS mapping capabilities.
The equipment is designed to provide cm accuracy. However, on its own, GNSS is not capable of providing the cm accuracy
required for many survey applications. GNSS needs to be fine-tuned using stationary base stations that provide correction
gures for all measurements. The real-time Kinematic (RTK) corrections are supplied from a central server (Trip Caster) via the
cellular phone network and the Cloud.

This set-up procedure assumes the operator has a suitable data-enabled SIM card registered with a cellular network provider and
that the operator has registered with an RTK provider. It is also assumed that the operator has the latest version of MyLocator3
installed on a computer. (see the section on MyLocator3).
Three areas of set up are required before the cm accuracy GNSS can be used:
1. SIM set-up
2. RTK connections with MyLocator3
3. Cloud (VMMAP based data logging)
2.7.1 SIM Set-up
Data is received and transmitted from the vLoc3 via a cellular network of your choice.
Needed: nano-size data-enabled SIM card
Tools needed: Small cross blade screwdriver
1. Remove the expansion slot cover by unscrewing the two retaining screws.
The SIM card slot is positioned between two micro USB sockets. The USB sockets are used in manufacturing only so they should
be ignored.
2. Insert the nano-sized SIM card connection pads facing upwards towards the display.
Make sure the SIM card is pushed fully into place.
To remove the nano-SIM card, push the SIM in to unlatch it before it is released.

2.7.2 Set up the RTK connections using MyLocator3
Download and install the MyLocator3 desktop app. The app can be downloaded from the Vivax-Metrotech website under
Products > Apps.
1. Connect the locator to the computer running the MyLocator3 app with the provided mini-USB cable.
2. Launch the MyLocator3 app, and a screen like the below will appear. Note the purple Update Now box will appear when an
update is available.
3. Click on the icon, which allows you to set the cloud settings as shown below.
4. Network "apn:" should be adjusted to the Access Point Name for your chosen Mobile network – be sure not to add any
spaces before or after the APN. If you do not have the APN, it should be possible to do a quick web search on “APN
settings for a mobile network.”
5. NTRIP settings should match your preferred NTRIP caster settings. If you have subscribed to an RTK provider, they will
give you your Caster address, caster port, Username, and password.
6. Click on the Icon on the toolbar. This sends the settings to the locator.
