Peripheral units 1 and 2 cannot be driven simultaneously. To drive themcontinuously, set the duty cycle ratio to 20% or less (excluding an externallyconnected buzzer).2. The following external buzzer is available as an option.External buzzer model: RMB-24Voltage rating: 24VAverage consumption current: Max. 21 mA (at 24V)Sound pressure: Min. 75 dB at 1 mLead wires: red (+) black (-)3. Never use the external buzzer command if you connect a device (such as acash drawer) other than an external buzzer. It could damage the connecteddevice and the printer circuit. Refer to the separate Programmer's Manual fordetails on commands.4. The status of the compulsion switch can be known from the status command.Refer to the separate Programmer's Manual for details.5.
