When the battery is nearly depleted, you will hear three short beeps repeated once a minute. If
you hear this warning signal while on a call, you have approximately 3 minutes left before the
handset will switch off.
About Silent Charging
Use Silent Charging if you don’t want calls to ring your OP27 phone while it is charging. Typically,
you use this feature if your Mitel IP Phone has been associated (programmed into a suite on the
3300 ICP) with your OP27 phone. Then, while your phone is charging, calls to your extension will
now only ring on your Mitel IP Phone.
If Silent Charging is active while the handset is in the charger, “Silent Charging” will appear in
display and the handset is disengaged from the system. When you remove the handset from the
charger, it is automatically engaged with the system and you can make and receive calls again.
