2. KEYBOARD AND LED DESCRIPTION
ON/OFF Key
Press the ON/OFF key until the Status led starts blinking to turn on the printer, then
release the key.
Press the ON/OFF key until the Status led remains on to turn off the printer, then re-
lease the key.
To access the configuration mode, press the ON/OFF key and the MENU key to turn on
the printer: when the paper roll starts advancing, release both keys (see chapter 3.4,
Setup description).
MENU key
When the printer is on, press the MENU key to advance paper by two lines.
When you turn on the printer, press the MENU key with the ON/OFF key to activate
the printer configuration mode.
POWER Led
The POWER Led provides information on the rechargeable battery status.
When you connect an external power supply, the printer checks rechargeable battery
status and, if necessary, it starts charging batteries.
A precharge phase may precede the real charge in order to avoid excessive stress on
batteries when they are significantly discharged or their temperature is too low: in
this phase the POWER led blinks every second.
After this first phase, the quick charge starts: the POWER led remains on and it turns
off when the battery is fully charged.
At this point you can disconnect the external power supply and use rechargeable bat-
teries only.
Warning: if you connect an external power supply and the POWER led turns off im-
mediately instead of lighting, it means that there is a fault or there are no batteries.
STATUS Led
The STATUS led shows the printer status. If the led blinks every two seconds, it
means that the printer is on and ready to print. If you disable the automatic switch -
off, the led blinks twice every two seconds (to set automatic switch-off, see paragraph
3.4.1 point 3).
