Key

SEEK/MAN UP

SEEK/MAN DOWN

Functional Description

• Hour digit adjustment

Each time SEEK/MAN DOWN key is pressed, hour advances by 1 hour. If key is held down for more than

0.5 second, hour is incremented in fast-forward mode by 1 hour every 200 ms, until key is released.

Minute digits and second count value are not affected.

• Minute digit adjustment

Each time SEEK/MAN UP key is pressed, minute advances by 1 minute. If key is held down for more

than 0.5 second, minute is incremented in fast-forward mode by 1 minute every 100 ms, until key

is released.

No carry to hour digit occurs.

Each time adjustment is made, second counter is reset.

During adjustment, colon remains lighted.

When MESEL switch of initial setting diode = 1 (shorted with diode), this key is used to enable preset

memory to be written.

When data is written to preset memory, beep sound is issued for about 40 ms.

This key is invalid when MESEL switch = 0 (open).

q During frequency display

This key is used to enable preset memory to be written.

When this key is pressed, data can be written to preset memory for about 5 seconds from point

at which key is pressed. By pressing any of the

M1

to

M5

keys, currently re-

ceived frequency is written to preset memory corresponding to pressed key. If

ME

key

is held down at this time, frequency cannot be written.

In memory write-enable status, operation of each key is as follows:

ME

Key
