Test Mode/Entry

Test Mode allows radio checks to be performed in the

1. Place radio in TRUNKING operation mode
and wait for 6 seconds. (See Quick Start card
for instructions on how to enter that mode.)
2. Turn radio off.
3. Verify that RIB is off.
4. Turn radio power supply (13.6 V DC) on for
35 W model or (13.8 V DC) for 15 W model.
5. Turn radio on.
The radio enters Test Mode operation:

Test Mode/Channel Selection

Use the PTT switch for channel selection. A short press
and de-press on the PTT switch (button-like push) will
advance the radio to the next channel (cyclical) . Seven
channels are available during test mode, as shown in
the table below.

Test Mode/Tx Modulation

Use PTT switch for modulation type selection. A con-
tinuous press will advance the radio to the next modu-
lation test (cyclic scroll ) and perform Tx test until PTT
is released. The modulation selection is described in
the table below.
