Chapter 2 Setup
Connecting the Optional External Buzzer
When the optional external buzzer (model: OT-BZ20) is connected to the drawer kick connector of the printer,
you can set the printer so that it beeps when you send commands, when an error occurs, when executed auto
cutting, and when detected paper end. Settings for sound patterns and frequency depending on the occasions
the buzzer beeps are also available.
Use the TM-T20III Utility to make the buzzer settings: enable/disable setting, sound pattern setting, and
frequency setting.
Connecting Procedure
The optional external buzzer is recommended to be installed in the following positions.
• When using the printer horizontally: either side
• When using the printer vertically or on a wall: either side/top/bottom (only for wall hanging installation)
• Be sure to turn off the printer before you connect/disconnect the optional external buzzer.
• The optional external buzzer and the cash drawer cannot be used simultaneously. Do not
connect both the optional external buzzer and the cash drawer to the printer at the same time
by using a branched connector.
• Do not install the optional external buzzer at the roll paper exit.
• To prevent liquid from entering inside, it is recommended to install the optional external buzzer
so that the volume adjustment knob is positioned sideways or downward.
