Description
The GAI-Tronics 6-Channel Radio is a stationary-mounted UHF transceiver suited for industrial
complexes, especially in cranes or other mobile equipment. It has a heavy-duty housing and includes a
choice of power sources (270 V dc or 110/220 V ac), microphones, speakers, and antennas. It has a
choice of 2-watt or 5-watt RF output, and CTCSS for private communications is selectable.
The radio measures 11.25 W 14.14 H 3.00 D inches. The housing is also a mounting bracket, and
includes an integral handle. The mounting bolts double as support feet when the unit is placed
horizontally on a flat surface such as on a desktop.
The channel selector switch and the power, speaker, and microphone connectors are located on the top of
the unit. The antenna connection is on the underside of the unit and remains easily accessible when the
unit is mounted. Refer to Figure 2 and Figure 3 below.
The standard power supply is nominal 120 V ac. There are 110/220 V ac or 270 V dc power supply
options available. Added filtering is standard for the 270 V dc option. The Radio Transceiver Module is
easily replaceable in the field, but must be reprogrammed by a qualified technician.

Radio T ransceiver Mo dule
The Radio Transceiver Module’s range is 450–470 MHz, and the six channel frequencies can be
programmed in steps of 12.5 kHz at the factory to the customer’s specifications. The Radio Transceiver
can also be programmed for CTCSS or DPL.
NOTES:
1. When the Radio Transceiver Module is programmed for CTCSS or DPL it can only communicate with
other radios that have the same CTCSS or DPL programming.
2. Certain transmit and receive frequencies within the radio’s range are unavailable. Refer to Table 5
below for these frequencies. Do not attempt to program the radio for these frequencies.
