7.3.2.9.1 Channel Number Selection
The steps in this section form a selection process, which must be performed for either new or existing
Channels. This process establishes the Pre-set Channel Number where later setting choices will be
stored. User actions after this step will depend on whether an existing Channel is being selected for
modification or a new Channel is being established.
If the user is modifying an existing Pre-set Channel setting, proceed as follows: Complete the selection
process described in this heading. Proceed directly to the heading that covers the setting to be modified.
If the user is establishing a new Pre-set Channel, complete the selection process described in this
heading. Complete ALL remaining headings in this section.
Channel Selection Process
Depress the Channel key (‘CHAN’) at 2. The Operational Display will display ‘CH’ at 3 and Channel
Digits at 4 will go blank.
Using the Numeric Keypad at 5, key in the desired Channel Number to be selected. The keyed in
Channel Number now will appear at 4. Depress the Enter (‘ENTR’) key at 6 to select the keyed in
Channel Number. All later settings entry and storage steps will be associated with this Channel
Number.
Proceed to the next step as previously described.
