UNIT KEYS
Options Key
There are many user programmable options under the
OPTIONS key. The OPTIONS key is used to scroll
through the list of options by repeatedly pressing the
OPTIONS key. After the selected option has been dis-
played, the ↑ (UP) and ↓ (DOWN) arrow keys are then
used to change that particular option. After the option
is changed, the ENTER/ADV key must be pressed to
enter the data into memory.
Many of the OPTIONS displayed are
only programmable under the SERVICE
MODE and not under the OPTIONS key.
Options only programmable under the
SERVICE MODE are noted in the details
describing the option.
Figure 32 on page 139 shows the programmable op-
tions. Following are the displays in the order they ap-
