3 FREQUENCY SETTING

Read me first

The IC-R8500 uses memory channels for storage of frequencies (as well as mode, tuning steps, etc.). When turning power OFF or changing memory chan- nels, the previously displayed frequency cannot be recalled unless it has been stored into a memory channel. Therefore, when you want to keep a dis- played frequency for later recall, you must program it into a memory channel by pushing [MW] for 1 sec.

kHz

USR-A BLANK

“BLANK” appears in the memory name area until [MW] is pushed for 1 sec.

Push [MW] for 1 sec. after tuning.

Convenient:

Use [M-SET] to program a displayed frequency (and its mode, etc.) without overwriting the currently select- ed memory. See p. 19.

Using the keypad

Push the numeral keys on the keypad to enter the MHz digits for the desired frequency.

If a key is mistakenly pushed, push [CE s] and start again from the beginning.

When entering the same MHz digits as the displayed frequency, this step can be skipped.

Push [ • t].

Push the numeral keys to enter the frequency digits below 1 MHz.

If a key is mistakenly pushed, push [CE s] and start again from the beginning.

Push [ENT] to set the input frequency.

When pushing [ENT] after entering the MHz digits, zeros are automatically entered for the kHz digits.
