Power-on Microprocessor Reset Procedure
Some or all transceiver settings can be reset to their factory-default states using one of the
following power-on routines:
+ POWER on: Reset all memories and following menu setting to factory-default.
Menu #06 (AM STEP), 23 (DCS CODE), 30 (FM STEP), 35 (MEM TAG), 42 (RPT
SHIFT), 47 (SSB STEP), and 48 (TONE FREQ).
+ POWER on: Reset all menu setting (except following menu) to factory-default.
Menu #06 (AM STEP), 23 (DCS CODE), 30 (FM STEP), 35 (MEM TAG), 42 (RPT
SHIFT), 47 (SSB STEP), and 48 (TONE FREQ).

BAND DATA FORMAT
The FT-818 BAND DATA Format (available on the ACC jack) is presented below. The
BAND DATA line provides a stepped voltage, which denotes the current operating band.
This data may be interpreted by an external device (such as an antenna switch or ampli-
er)to provide automatic band switching.
BAND LEVEL BAND LEVEL BAND LEVEL BAND LEVEL
1.8 MHz 0.33 V 10 MHz 1.33 V 21 MHz 2.33 V 50 MHz 3.33 V
3.5 MHz 0.67 V 14 MHz 1.67 V 24.5 MHz 2.67 V 144 MHz 3.67 V
7 MHz 1.00 V 18 MHz 2.00 V 28 MHz 3.00 V 430 MHz 4.00 V
Use shielded cable for interconnections to external devices, so as to prevent RF interfer-
ence.
