Introduction

•Additional Information Sheet
•G277/577 Quick Reference Guide
Notice on the use of the handsets
Like all cordless telephones, the G277/577 DECT handset uses
radio signals, which do not guarantee a connection under all
circumstances. Do not rely exclusively on the DECT handsets
when making indispensable calls (such as medical emergencies).
SOS functions
The SOS functions of the G577 do not replace companion
supervision by a colleague or other people. In case of critical,
emergency or life-threatening situations make sure that other
persons are present or that appropriate measures are taken.

160 hours of standby time.

when placed in the charger.
