IO.5 MHz1

When the scan, starting from 431.637.5 MHz, reaches the upper limit 431.987.5 MHz, it jumps down to the lower limit 431.500.0 MHz where the scan is started again. This action is repeated while holding 0.5 MHz width.

(1 MHz]

When the scan reaches from 431.637.5 MHz to the upper limit 431.987.5 MHz, it jumps down to the lower limit 431 .OOO.O MHz and reaches 431.987.5 MHz again. This action is repeated while holding 1 MHz width.

[3 MHz]

Similarly, when the scan reaches from the lower limit 431 . 000 . 0 MHz to the upper limit 431 . 637 . 5 MHz, it jumps down to the lower limit and reaches the upper limit again. This action is repeated while holding 3 MHz width.

The lower limit is 431.637.5 MHz minus the frequency on 100 kHz Order, and the upper limit is 433.987.5 MHz, one step lower than 434.000.0 MHz which is the lower limit plus 3 MHz but the scan Starts from 431.637.5 MHz. [5 MHz1

The upper and lower limits are calculated in the same manner as for 3 MHz width. The scan is repeated between the lower limit and the upper limit while holding 5 MHz width.

[lO MHz]

The scan is repeated between the upper limit 4 3 9 . 9 8 7 . 5 M H z a n d t h e l o w e r l i m i t 4 3 0 . 0 0 0 . 0 M H z while holding 10 MHz width.

Note 1: In the SCAN W Position 3, 5 or 10, the scan in the 144 MHz band is repeated between the upper limit 145 . 987 . 5 MHz and the lower limit 1 4 4 . 0 0 0 . 0 M H z .

Note 2: In these Position, the scan does not shift over the 144 and 430 MHz bands. For example, when the SCAN W is 5 in 438.250.0 MHz, the scan is ef- fected holding 5 MHz width.

Note 3: The scan width should be calculated even in the following cases:

1) When VFO (A, B) is switched.

2)When SCAN W switch is set to another posi- tion.

3)When BAND switch is depressed.

Note 4: The scan width remains unchanged when the SCAN switch is depressed for BUSY stop.

To Change the scan width, the scan should be released.

Note 5: The BAND switch can be used during scan opera- tion, but it does not function continuously when it is kept depressed. This switch also functions even when the F. LOCK switch is ON.

The scan is released when the PRIO. M, MR or MS switch is set to ON.

5-15 USE OF MS (MEMORY SCAN) SWITCH

When the 144 MS or 430 MS switch is set to ON, the function (CH No.) flickers to indicate that the memory channels (l-l 0 ch) can be scanned (the squelch threshold should be set as in the case of VFO scan).

With the 144 MS switch ON, the memory channel for 144 MHz band can be scanned. With the 430 MS switch ON, the memory channel for the 430 MHz band is scann- ed. When both switches are ON, all the channels (both for 144 and 430 MHz bands) are scanned. To hold the scan, use the procedure for VFO scan. To restart the scan, set the SCAN switch to ON.

Note 1: Scan is not effected when the SCAN switch is kept depressed.

Note 2: When scan is held in the ON Position of both MS switches, it can be restarted by setting either switch to OFF or by pressing the CALL or MR switch.

Note 3: When all the channels are 144 MHz band and the 430 MS switch is set to ON, the function flickers quickly and a oscillation Sound is heard con- tinuously. This also occurs when all the channels are 430 MHz band and the 144 MS switch is set to ON.

Note 4: Only memorized channels are scanned.

5-l 6 USE OF PRIO. M CHANNEL

With the PRIO. M 9 or 10 switch set to ON, stored fre- quencies in the memory channels 9 or 10 can be recalled with first priority. In the channel 9 and 10. 145.000.0 MHz and 433.000.0 MHz are preset respec- tively, while any frequency can be memorized in each channel. Display of the PRIO. M channel is as follows:

c :5;5,UfiQ,G o r c $r_r(J,fia2,U

Note: 1 The PRIO. M 9 is Prior to the PRIO. M 10.

Note: 2 The PRIO. M channel frequency is displayed to 100 Hz digit.

5-17 BACKUP OF MEMORY CHANNEL FRE- QUENCY

Any desired memory channel frequency can be stored in the RAM (Random Access Memory) of the micro- Computer. But the data (frequency) in the RAM is cleared when the power switch is set to OFF. The transceiver has its own built-in backup circuit to hold the data (frequency) even when the power switch is OFF during both AC and DC operations. By loading backup battery in the transceiver battery case, the battery power is always supplied to the backup circuit . In this way, the data is not . cleared regardless of the Position of the power switch. The backup
