. Place the antenna upright in a suitable position to give optimum

pressing the green CANCEL button while the Liberty
300
alarm is in normal/
operation mode. The signal strength will be displayed for two seconds and
updates every minute.
The base alarm unit will display the signal strength from
0 to 9.

2-5 = Average signal
6-9 = Strong signal
Note: A higher gain antenna is available for purchase for clients in poor GSM
coverage areas. View Tunstall Healthcare contact details on page 12.
