Note: The communication Parameters: Baud rate, Data Bit and Parity must be set the same
as the host device settings. Dip switch #1 must be in the OFF position.
3.4 Infrared Communications (IrDA)
Dip Switch #1 must be in the <ON> position.
The printer can be powered up by pressing the power <On/Off> switch.
If no IrDA connection is made, the printer will automatically power down to a lower
power level to conserve battery life. It will remain in a “sleep” mode until an IrDA
connection is made, at which time the printer will “wake” up and print the requested
data.
Pressing the power switch again will turn the printer <OFF>.
