User Safety, Training, and General Information
READ THIS IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION
BEFORE USING YOUR HYT PORTABLE REPEATER.
Compliance with RF Energy Exposure Standards
Your HYT portable repeater is designed and tested to comply with a number of national
and international standards and guidelines (listed below) regarding human exposure to
radio frequency electromagnetic energy. This repeater complies with the IEEE (FCC) and
ICNIRP exposure limits for occupational/controlled RF exposure environment at duty
cycles of up to 50% talk-50% listen and should be used for occupational use only. In terms
of measuring RF energy for compliance with the FCC exposure guidelines, your repeater
radiates measurable RF energy only while it is transmitting (during talking), not when it is
receiving (listening) or in standby mode.
Your HYT portable repeater complies with the following of RF energy exposure
standards and guidelines:
United States Federal Communications Commission, Code of Federal Regulations;
47CFR part 2 sub-part J
American National Standards Institute (ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992
Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition
International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Operational Instructions and Training Guidelines
To ensure optimal performance and compliance with the occupational/controlled
environment RF energy exposure limits in the above standards and guidelines, users
should transmit no more than 50% of the time and always adhere to the following
procedures:
4
Transmit and Receive
To transmit (talk), push the Push-To-Talk (PTT) button of the optional microphone; to
receive, release the PTT button.

FCC Compliance
Part 15 Compliance
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
　 Reorient or relocate the receiving antenna.
　 Increase the separation between the equipment and receiver.
　 Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
　 Consult the dealer or an experienced radio/TV technician for help.
FCC Licensing Requirements
Your repeater must be properly licensed Federal Communications Commission prior to
use. Your HYT Wireless dealer can assist you in meeting these requirements. Your dealer
will program each repeater with your authorized frequencies, signaling codes, etc., and
will be there to meet your communications needs as your system expands.

Features and Operations
Basic Operations
1. Switch the AC power on: properly connect the AC power cord and then switch the
power on.
2. Turn the repeater on: rotate the Power/Volume Control Knob clockwise until a click
sounds to turn the repeater on, LED glows red.
3. Enter Repeater Mode: turn on the repeater to enter standby mode. Transmitter and
receiver LED glow simultaneously when a valid signal is detected.
4. Adjust the volume: rotate the Power/Volume Control Knob in Repeater Mode. Adjust
the volume to the minimum level when monitoring is not needed.
Time-out-Timer (TOT)
Time-out-Timer is used to prevent one from using the same channel for a long time and to
prevent the transmitter from damage due to continuous transmission. If the transmission
exceeds the preset time (it’s set by your dealer, max. time is 10 minutes), transmission will
be forbidden. Release the [PTT] key and press it again to resume transmitting.

CTCSS/DCS Signalling
CTCSS/DCS may have been programmed on a channel to ignore unwanted calls from
other parties on the same channel.
When CTCSS/DCS signalling is set, the user can only receive calls from other parties
which are using the same CTCSS/DCS signalling on the same channel within
communication range; otherwise, the user receives all the calls on the same channel
within communication range.
CTCSS/DCS signalling can be preset by your dealer.
Note: Although using CTCSS/CDCSS enables you to avoid hearing unwanted calls, it
doesn’t mean all your calls will be private.

Troubleshooting Guide
Trouble Solution
Fail to turn the repeater on Check if the AC/DC power supply cord is
properly connected, or the AC switch fuse
is blown.
Make sure you are using the same
frequency and CTCSS/DCS as the
repeater.
Can’t talk to or hear group members
Make sure you are within the coverage of
repeater.
Other voices (Non-group members) appear
on the channel
Change CTCSS/DCS of the repeater.
Make sure all the radios of your group
are changed to the same signaling.
Care and Cleaning
◇ Place the repeater in dry, ventilated and waterproof indoor environment;
◇ Clean the repeater shell with wet cloth or neutral detergent.
