Turning On and Turning Off
16.1. Palm T|X On/Off
General
The Palm T
|
X can be turned ON in either of two ways: by pressing the green button on the top edge, or
by pressing any of the four keys below the display. Using the green button returns to the application in
use when it was turned off. Using one of the four keys below the display will go to the application
assigned to that key.
Note:
When turning the unit back on, it may be necessary to press a key several times before it
responds. This is because, in sleep mode, the keys are being polled very slowly as part of the power
saving system.
The Palm T
|
X can be turned OFF by pressing the green button on the top edge. When operating on its
battery and running standard Palm applications, it will turn off automatically after a short delay from the
last action (settable between 30 seconds to 3 minutes). This automatic switch off is disabled whenever
the mains adaptor/charger is connected (unless preferences are changed).
Within the PSAnalyzer Application
The PSA1301/2701T is most easily switched on or off using the hard key marked Back. When using the
PSAnalyzer application, pressing and holding this key for more than one second turns it off (sleep
mode). Pressing it again turns it back on.
Note:
It may be necessary to press the key more than once to turn on because of slow key polling in
sleep mode.
The PSAnalyzer application suppresses automatic switch off of the Palm T
|
X and replaces it with its own
battery saving system. Using the Auto Sleep function from the System menu, the unit can be set to turn
off automatically at a user set delay between 5 minutes and 60 minutes from the last button press.
Any of the four main hard keys can be used to turn the unit on, though the Back (Home) key is
preferable - because the other keys will also perform the function assigned to them. Alternatively the
green button on the top edge can be used for on or off.
16.2. PSA1301/2701 On/Off Control
The on/off state of the PSA1301/2701 spectrum analyzer unit is controlled from the Palm T
|
X.
If the T
|
X is ‘on’ and the PSAnalyzer application is running, then the PSA1301/2701 will be on. If the T
|
X
is ‘off’, or if the T
|
X is on but an application other than PSAnalyzer is running, the PSA1301/2701 will be
off.
16.3. Operation Delay after Turning On
When the PSAnalyzer application is brought out of Sleep mode (by pressing a hard key or the green
power key), the PSA1301/2701 goes through a brief initialisation sequence. This can create a delay of
up to two seconds during which the Run/Stop indicator turns red and shows Wait. It is also possible that
the first sweep may be corrupted.
