AR2700 operating manual

[CLR] - Clear entry key
This key will cause data entry to be cancelled should a mistake be
accidentally typed and forces an escape “back to search, scan or manual
mode” whichever had been previously selected. The [CLR] key is also used to
escape from the frequency pass menu.
There is no second function for this key.
Should you experience a programming / operational problem with the AR2700,
you may “soft” reset the microprocessor by holding the [CLR] key while
powering up the receiver. Your memory bank and search bank data will
remain intact but any linked bank settings etc will be lost. This has the same
effect as the external soft reset switch on the left hand cabinet... use only as a
last resort.
A FULL MICROPROCESSOR reset is accomplished by holding both the
[CLR] and [ENT] keys while switching On the unit using the [PWR] key.
All memory channels, search banks, pass channels etc will be lost and blank.
As a result the search and scan facilities will not operate until new data has
been entered. Note: It is quite normal for the set to take about 30 seconds
to recover from a FULL reset as all data is being deleted !!!
[ENT] - Enter key
The enter key is used to finalise the entry of frequency and other data inputs.
While in manual mode, press and hold the [ENT] key for more than 1.5
seconds to add the currently displayed frequency into memory.
While in SEARCH mode and stopped on a busy channel, press the [ENT] key
to write the current displayed frequency into memory.
The [ENT] key is also used during a FULL microprocessor reset.
5-8 Loudspeaker (internal)
The AR2700 is fitted with an internal front facing loudspeaker toward the
lower front cabinet. When an external earphone, headphone or speaker is
connected, the internal speaker is automatically disconnected.

5-9 [2ndF] Function key

[2ndF] (shift) key is used to access the second key functions as listed
underneath the keypad keys. Other functions may also be accessed
using the function key.
