6. To exit the Adjustment Mode, turn the transceiver OFF.
Note:
• When you press [LAMP] or [MONI] key, ensure the bosses
of rubber keys align with the LAMP and MONI contacts of
the PTT PCB (C/3).
• In the Adjustment Mode, Transmission and Reception
frequencies becomes extensive.
A. Overvoltage warning reference voltage (14.8V [DC IN])
(1)Press the [LAMP] or [MONI] key on the transceiver to display
“DC” on the LCD.
The current voltage value is displayed at the lower digits of
the frequency display, and the value stored in the EEPROM
is displayed on the memory channel number display.
(2)Press the [MENU] key to write the current voltage value
into the EEPROM.
B. Battery terminal reference voltage (7.5 V [Battery
terminal])
(1)Press the [LAMP] or [MONI] key on the transceiver to display
“BAT” on the LCD.
Press the [F] key and then the [PTT] key repeatedly to turn
the “
” icon ON. The current voltage value is displayed at
the lower digits of the frequency display, and the value
stored in the EEPROM is displayed on the memory channel
number display.
(2)Press the [PTT] key to enable the transmit mode.
(3)Adjust the output voltage from DC power supply until the
voltage at the battery terminal becomes 7.5V while the
transceiver is transmitting.
(4)Press the [MENU] key to write the current voltage value
into the EEPROM.
C. Squelch (SQL1, SQL2)
1Squelch (SQL1)
(1)Press the [LAMP] or [MONI] key on the transceiver to display
“SQ1” on the LCD.
The detected DC voltage value to the current noise level is
displayed at the lower digits of the frequency display, and
the value stored in the EEPROM is displayed on the memory
channel number display.
(2)Press the [MENU] key to write the current noise level value
into the EEPROM.
2Squelch (SQL2)
(1)Press the [LAMP] or [MONI] key on the transceiver to display
“SQ2” on the LCD.
(2)Press the [MENU] key to write the current noise level value
into the EEPROM.
