Paxar Mobile Work Station (MWS) Monarch 9878 - Manual (Page 28)

A b o u t S l e e p M o d e
If the Monarch® 9800 ä printer is inactive for longer than 30 seconds, the
printer goes into sleep mode to conserve battery power. While in sleep
mode, the display backlight is turned off to conserve battery power. Once
the printer “wakes up,” the backlight turns on.
To “wake up” the printer, press any button on the control panel. The buttons
are active during sleep mode, so if you press Escape/Clear, the printer
“wakes up” and you enter the offline menu mode. You can also send any
data to the printer to wake it up. You do not lose any data sent to the
printer during sleep mode.
