TROUBLESHOOTING

The problems described in this table are commonly encountered operational malfunctions. These types of difficulties are

usually caused by improper hook-up, accidental incorrect control settings, or operator error due to incomplete programming.

These problems are usually not caused by circuit failure. Please review this table, and the appropriate section(s) of this

instruction manual, before assuming your transceiver is defective.

Note:

When 2 frequencies are received in the same band and these frequencies have relationships per the equation below or other similar relationships,

an internal heterodyne may be heard. This is not a defect.

1 The power cable was connected

backwards.

2 One or more of the power cable

fuses are open.

3 The front panel was not connected

securely to the main unit of the

transceiver.

4 The connectorized cable was not

correctly connected.

1 Connect the supplied DC power cable

correctly:

Red ➞ ( + ); Black ➞ ( – ).

2 Look for the cause of the blown fuse(s).

After inspecting and correcting any

problems, install a new fuse(s) with the

same ratings.

3 Separate the front panel from the main

unit by using the release switch on the

rear of the front panel, then lock the front

panel securely to the main unit by using

the same switch.

4 Connect the connectorized cable correctly.

VHF/UHF mode: (UHF receive frequency – 45.05 MHz) x 2 – (VHF receive frequency + 38.85 MHz) x 4 = 38.85 MHz or 45.05 MHz

(UHF receive frequency – 45.05 MHz) – (VHF receive frequency + 38.85 MHz) x 2 = 38.85 MHz

VHF/VHF mode: (VHF receive frequency on the UHF band + 45.05 MHz) x 5 – (VHF receive frequency on the VHF band + 38.85 MHz) x 5 = 38.85 MHz or 45.05 MHz

(VHF receive frequency on the UHF band + 45.05 MHz) x 4 – (VHF receive frequency on the VHF band + 38.85 MHz) x 4 = 38.85 MHz

(VHF receive frequency on the VHF band + 38.85 MHz) – (VHF receive frequency on the UHF band + 45.05 MHz) x 0.75 = 38.85 MHz

UHF/UHF mode: (UHF receive frequency on the VHF band – 38.85 MHz) x 3 – (UHF receive frequency on the UHF band – 45.05 MHz) x 3 = 38.85 MHz or 45.05 MHz

(UHF receive frequency on the VHF band – 38.85 MHz) x 4 – (UHF receive frequency on the UHF band – 45.05 MHz) x 4 = 38.85 MHz or 45.05 MHz

The transceiver will not

power up after connecting

a 13.8 V DC power supply

and pressing the

(POWER) switch.

Nothing appears on the

display.
