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:

Due to frequency relationships of some circuits in this transceiver, beat tones may be heard on the following frequencies: 10.000 MHz, 20.000 MHz and 30.000 MHz. This is not a fault.

Placing a powered handy transceiver near this transceiver may cause noise in this transceiver.
