NOTES: • Pressing the Off key after entering only one or two digits restores the cordless
handset to the standby state.
• Entering an invalid function code does not display any error message so that the
cordless handset superficially appears to accept the entry. If you make a mistake in
entering a code, therefore, press the Off key to return to the standby state and then
go back to the beginning of the procedure.
