Overview of the Test Mode
The test mode has been build in the microprocessor in order to confirm the performance
of transceiver.
The purpose is to adjust transceiver simply and to confirm the performance of
transceiver smoothly.
(A) Expansion channels “EXP01 - EXP06” will be set as follows:
DISPLAY
RX Frequency
TX Frequency
EXP01
156.050 MHz
156.050 MHz
EXP02 ---
157.425
MHz
EXP03 163.275
MHz
---
EXP04
155.050 MHz
155.050 MHz
EXP05
162.025 MHz
162.025 MHz
EXP06
163.575 MHz
158.975 MHz
(B) In CH70, every time you are in transmit mode, (every time you press PTT), the
following test tone can be outputted:
1st transmission: Synthetic tone of 1300 Hz and 2100 Hz
2nd transmission: 1300 Hz
3rd transmission: 2100 Hz
4th transmission: No modulation
5th transmission: Return to 1st transmission
(C) Scan the channels between WX10 and EXP04 in the SCAN mode.
(D) In the test mode, a transmit time-out timer function (TOT) becomes off.
(E) A user’s MMSI is set to “0123456789” for DSC tests tempor
Starting the Test Mode
Press the [
PWR
] switch while pressing and holding the [
DISTRESS
] and [
WX
] keys to turn
on.
Confirmation of VCO
Connect the DC voltmeter to the test point (LOCK TP).
Set the channel to
EXP06
, confirm that the voltage on the
TP1013
is more than 0.25V
during receiving.
Set the channel to
EXP04
, confirm that the voltage on the
TP1013
is less than 3.8V
during transmitting.
