5-6-8. Open channel search step size selection
(TM-3530A/2570A/2550A/2530A only)
Cut the diode D22 to change the open channel search
step size for channel linkage from 1 5 kHz to 20 kHz
(from 20 kHz to 40 kHz with the TM-3530A) steps.
Note:
When the diode (D22) is cut, reset the microprocessor
using the procedure on page 15.
5-6-9. Microphone UP/DWN step size and scan
step size selection (TM-2550E only)
The microphone UP/DWN step size and scan step size
can be changed to 1 2.5 kHz by cutting D12 on the con­
trol unit (X53-1440-10). However, frequency entry by
use of the numeric keypad is still possible in either 5 kHz
or 12.5 kHz steps.
Note:
When the diode (D12) is cut, reset the microprocessor
using the procedure on page 1 5.
5-6-10. Microprocessor reset pins
When the microprocessor reset using the procedure on
page 15 is unable or the lithium battery is replaced, short
these two pins while depressing the PS key.
5-6-11. Call sign monitor test pins
The test pins are short-circuited to monitor the own call
signal when the Call Sign Display option is used. Be
careful of noise interfering with the reception due to this
operation.
