IC Unlicensed Devices EIRP Statements for Removable Antennas
Part 1: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Partie 1 : Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal
(ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres
utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication satisfaisante.
Part 2: This radio transmitter (LOBSRF-305) has been approved by Industry Canada to operate with the antenna type listed below with the
maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a
gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
Partie 2 : Cet émetteur radio (LOBSRF-310) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant
un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est
supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.

Cervis, Inc. Safety Precautions
✓Read and follow all instructions.
✓Failure to abide by Safety Precautions may cause equipment failure, loss of authority
to operate the equipment, and personal injury.
✓Use and maintain proper wiring. Follow equipment manufacturer instructions.
Improper, loose, and frayed wiring can cause system failure, equipment damage, and
intermittent operation.
✓Changes or modifications made to equipment not expressly approved by the
manufacturer will void the warranty.
✓Equipment owner/operators must abide by all applicable Federal, State, and Local
laws concerning equipment installation and operation. Failure to comply could result
in penalties and could void user authority to operate the equipment.
✓Make sure that the machinery and surrounding area is clear before operating. Do not
activate the remote control system until you are certain that it is safe to do so.
✓Turn off the handheld remote and remove power from the base unit before attempting
any maintenance. This will prevent accidental operation of the controlled machinery.
✓Remove power from the Base Unit either by detaching the 12-pin cables from the
base unit connectors P1 and P2, or by removing the source power from the circuit.
✓Use a damp cloth to keep units clean. Remove mud, concrete, dirt, etc., after use to
prevent obstructing or clogging the buttons, levers, wiring, and switches.
✓Do not allow liquid to enter the handheld or base unit enclosures. Do not use high-
pressure equipment to clean the handheld remote or base unit.
✓Disconnect the radio base unit before welding on the machine. Failure to disconnect
the base unit may cause destruction of or damage to the base unit.
✓Operate and store units only within the specified operation and storage temperatures
defined in this document’s specifications.
✓Do not key two-way radios while using the handheld remote.

User Manual
1.0 SmaRT Link Booster (SLB) Introduction
The SmaRT Link Booster (SLB) is a 900 MHz@10 mW or 2.4 GHz @ 100 mW line-of-sight
communications booster designed to extend the communication range between a 900 MHz
SmaRT remote control unit and a 900 MHz SmaRT base unit or a 2.4 GHz SmaRT remote
control unit and a 2.4 GHz SmaRT base unit. The SmaRT Link Booster is particularly useful
when the handheld remote and the base unit are not in line-of-sight of each other, in which case
the SLB is positioned so that it is in line-of-sight of each unit—at the corner of a structure, for
instance—where the structure would typically block communications between the handheld and
the base unit.
Figure 1. SmaRT Communications Link Booster
The SLB comes with four magnets installed inside the back of the case that can be used to
attach the unit to any ferrous surface. Two single-use or rechargeable “C”cell batteries power
the SLB. The SLB allows users to select the type of battery preferred. The removable swivel
antenna can be oriented as vertical, at a 45° angle, or at 90° allowing optimal signal strength.

2.0 Installing “C” Cell Batteries
Typically, two single-use or rechargeable “C”cell batteries power the SLB. Follow these steps to
install the power source in the SLB.
1. Remove the battery cradle cover.
2. Insert two single-use or rechargeable “C”cell batteries into the cradle, negative
end first.
3. Install the battery cradle cover by pushing against the positive end of the
exposed battery with the cover while turning the cover clockwise until it is fully
seated.
Figure 3. Installing the SLB Batteries
Caution!
Observe proper polarity when placing batteries into the
cradle. Improper battery placement can cause excessive
heat, battery explosion, operator injury, and damage to
the unit.

3.0 Choosing the Battery
You must select an initial battery, due to the voltage differences between standard single-use
and rechargeable batteries. Make this selection whenever you change to a different stylebattery
–alkaline to Lithium Ion, or Lithium Ion to alkaline. Follow these steps to choose which battery is
used.
1. Power down the SLB by holding Power button for three seconds. The display will
be unlit.
2. Simultaneously press and hold the UP and DOWN buttons. Then, press and
release the green power button. The display will read BAT MENU.
3. Simultaneously release Buttons 1 and 2. The display will read =A =LI.
4. Select to choose single-use (alkaline) batteries. Select to choose
rechargeable (Lithium Ion) batteries.
The SLB immediately changes to the selected battery and will remain in service until shut down.

5.0 Using the SLB
5.1 SLB Power On
Turn on the SLB by pressing the green power button located on top of the unit, next to the
battery tube cover. To conserve power, the unit shuts off the display when it is not in either scan
mode or menu mode. A blinking health indicator indicates that the unit is, in fact, powered on.
The TX and RX LEDs flash if the unit is paired with a HH and BU system.
Figure 9. SLB Power On
5.2 SLB Power Off
Turn off the SLB by pressing and holding the power button for three seconds. “PDOWN”
displays, goes out, and displays again. When the user releases the power button, the unit
powers down.
Figure 10. SLB Power Off
5.3 Establish SLB Communications Using Scan
The SLB must initially be set to scan for an associated handheld and base unit before it
communicates with them. The SLB establishes the communication links once it scans and finds
the system.
•If a handheld/base unit system is already associated (see your system manuals for details),
immediately use the scan feature to establish communications with the system.
•If the handheld/base unit that are going to be used as a system are not associated, then
use the Associate procedure detailed in the handheld remote manual or system manual
before using SLB scan.

Scan to Establish Communications
The SLB must initially scan for the system before it can be used. For the following steps,
assume that the handheld remote and base unit comprising the system are already associated.
Use the following instructions to scan for the system:
1. Turn on (power up) the handheld, base unit, and SLB with all devices in line of
sight of and near the SLB.
2. Press and hold the SLB UP button for three seconds.
3. When the SLB display reads “SCAN,”release the UP button, and wait while the
unit scans each channel. It will scan until if finds a valid message.
4. When the unit finds a valid message, it displays the Base Unit ID. (The Base Unit
ID is on the base unit’s front label.)
a. If the ID is the one you want, press the UP button to use this unit pair. The SLB exits
scan mode.
b. If the displayed ID isn’t the unit you desire, press the DOWN button. The SLB
continues to scan.
✓ Note: With multiple SmaRT Systems running, it is possible that a scan will list more than one
unit.
5. When the Link Booster is finished scanning each channel, it displays “DONE”.
Press the DOWNbutton to exit scan mode.
If the SLB found an acceptable base unit ID, the SLB Handheld TX/RX and Base Unit TX/RX
LEDs flash, indicating communications.
If the SLB did not find an acceptable base unit ID, the SLB Handheld and Base Unit LEDs
remain unlit–unless a previously established existing pair is on.
