Power management
The exact amount of time before the
PTC-1800 enters any mode depends
on how your PTC-1800 has been pro-
grammed.
The power management feature conserves battery
power by slowing down or deactivating internal
components of the PTC-1800. This feature is activated
in levels, or modes, depending on the unit's operation
and configuration.
Run mode
This is the PTC-1800's normal operating mode. All
resources are functional.
Suspend mode
Pressing the
On/Off
key terminates
any active telephone call(s). The unit
will not accept telephone calls while
suspended.
The PTC-1800 goes into suspend mode after
approximately 1 min. of inactivity or when the On/Off
key is pressed (see note below). During this mode, the
PTC-1800's screen goes blank, the backlight turns off,
and other subsystems inside the PTC-1800 may slow
down or turn off to conserve power. The application
program running at the time in which it is suspended,
and any data in RAM is protected.
