Compliance and Control Guidelines and Operating Instructions for Portable
Two-Way Radios to Control Your Exposure and Ensure Compliance with the
Occupational/ Controlled Environment Exposure Limits, Always Adhere to
the Following Procedures:
•Transmit no more than 50% of the time.To transmit (talk), push the Push-To-Talk (PTT) button.
To receive calls, release the PTT button.Transmitting 50%of the time or less is important since
the radio generates measurable radio frequency (RF) energy exposure only when transmitting
(in terms of measuring standards compliance).
•For body-worn operation, always place the radio in a JTECH approved belt clip or similar
accessory that contains no metallic components and provides a minimum separation distance
of 1.3 cm between the back of the radio and the user’s body. JTECH approved accessories,
antennas, and device combinations comply with the occupational/controlled environment RF
exposure limits. Using accessories not approved by JTECH may result in exposure levels which
exceed the FCC ’s occupational/controlled environment RF exposure limits. JTECH approved
accessories have been tested and comply with FCC RF exposure requirements.
•If you are not using a body-worn accessory and are not using the radio held in front of the face,
ensure the radio is kept at aminimum of 1.3 cm from the body when transmitting. Keeping the
radio at a proper distance is important since RF exposure decreases with increasing distance
from the antenna.
• Use only FCC approved, supplied or replacement headsets, batteries, and accessories intended
for use with this radio. Use of non FCC approved headsets, batteries, and accessories may
exceed FCC RF exposure guidelines.
Product Safety and RF Exposure for Portable Two-Way
Radios Compliance with RF Energy Exposure Standards
NOTICE: This radio is intended for use in occupational/controlled applications where users have
been made aware of the potential for exposure and can exercise control over their exposure. This
radio device is NOT authorized for general population, consumer, or similar use.
BEFORE USING THIS RADIO, READ THE TRAINING MATERIAL BELOW WHICH CONTAINS IMPORTANT
OPERATING INSTRUCTIONS FOR SAFE USAGE AND RF ENERGY AWARENESS AND CONTROL
INFORMATION FOR COMPLIANCE WITH RF ENERGY EXPOSURE LIMITS IN APPLICABLE NATIONAL AND
INTERNATIONAL STANDARDS.

Federal Communication
Commission (FCC) Regulations
The FCC has established limits for safe exposure to radio frequency (RF) emissions from radio devices. The FCC requires
manufacturers to demonstrate compliance with RF exposure limits before radio devices may be marketed in the U.S. When
two-way radios are approved for occupational/controlled environment exposure limits, the FCC requires users to be fully
aware of, and exercise control over, their exposure. Awareness and control of RF exposure can be accomplished using
labels, or by education and training through appropriate means such as information and instructions in user manuals or safety
booklets. Your JTECH two-way radio has an RF exposure information label in the battery compartment. The training material
below includes useful information about RF exposure and helpful instructions.
Your JTECH two-way radio device was designed and tested to comply with several national and international standards and
guidelines regarding human exposure to RF electromagnetic energy. In terms of measuring RF energy for compliance with
FCC exposure guidelines, your radio device radiates measurable RF energy only while transmitting (during talking), not when
it is receiving (listening), or in stand-by mode.

related use, transmit only when the person(s) is at least the minimum distance from the properly installed, externally
mounted antenna. Transmit only when people are outside the vehicle or away from the repeater antenna and are at least
the recommended minimum lateral distance away from the antenna/vehicle.

Monitoring aChannel
Monitoring allows you to check for activity on achannel. The JTECH Extend has three monitor modes. You can choose a mode
according to your preference.
•Squelch Off (Default): In this mode, the speaker is unmuted in any condition so as to receive any sound on the current
channel. When audio signal is received on the channel, audio will be heard. Otherwise, background noise will be heard.
Operation: Press and hold the Monitor (Default SF2) key to enter this mode, and release the key to exit.
•Monitor toggle: In this mode, the receiving party can receive incoming calls from the transmitting party regardless of
CTCSS/CDCSS condition. If the channel frequency is not the same, the receiving party will not receive any incoming calls.
Operation: Press the Monitor key to enter this mode, and press it again to exit.
•Monitor Momentary: Refer to Monitor toggle.
Operation: Hold down the programmed monitor key continuously to enter this mode, and release the key to exit.
You can scan up to 16 channels and frequencies. When the radio detects activity, it stops scanning and locks in on the
active channel. If programmed for talkback, you can talk and listen to the person transmitting without changing
channels.
NOTE: The icon will appear on the display when the current channel is added to the scan list. The icon will
appear on the display when the current channel is a priority channel.
1. To start scanning, press the key programmed as “Scan” (S/M default). The scan icon displays and the radio
begins to scan the channels. When the radio detects activity, it stops on that channel and displays and the channel
number.
2. To talk to the person transmitting without switching channels, press the PTT button before scan resumes. If no
transmission occurs, scanning resumes.
Note: these timers can be changed by the programming software.
3. To stop scanning, press the “Scan” Key. If you press PTT while the radio is scanning, the radio transmits on the
channel you were on before you activated scan.
Scanning
Skipping and Removing Channels While Scanning
Scan has two temporary features to make it easier to use.
1. Scan advance: If the radio stops scanning on a channel you do not want to listen to, press
2. Nuisance delete: Press and hold to temporarily remove achannel from the scan list. The channel returns to the scan
list when the radio is turned off &then on again.

Without Priority Channel
Providing that there is a scan list with 6 channels and all channels are non-prioritized, the normal scan operation would
proceed in the following sequence, as shown in Figure 1.
With Priority Channel
If you prioritize Channel 2as priority, the scan operation would proceed in the following sequence, as shown in Figure
2.
This function enables users to scan the most frequently used channel so that messages will not be missed. The priority
channel is programmed by the dealer via programming software or by the radio’s keypad if full radio programming is
activated.
Note: If the radios receiving on a non-priority channel, the priority channel is still scanned. The radio will switch to the
priority channel once any activity is detected.
Power-On Scan
If power-on scan is enabled by your dealer, the radio will automatically enter scan mode when it is turned on. The radio is
always in scan mode. Scan cannot be turned off.
