Gsm Network Signal Detection - Centurion G-SPEAK Installation Manual

8. GSM Network Signal Detection

When powered up, the G-SPEAK will beep three times and the signal strength indicator
LEDs will light up indicating the GSM network signal strength. The GSM signal strength
can be determined based upon the combination of the three LEDs that illuminate:
The GSM signal strength may be
enhanced by repositioning the
antenna. Ideally the antenna
should be mounted externally, and
away from any sensitive electrical
components.
The rear side of the antenna has a
double-sided tape backing, which
may be used to affix the antenna
to a desirable location.
Please ensure that the surface to
which you affix the antenna is
smooth, clean and dry, to ensure
reliable adhesion
10. Power up the GSM Module, hold the
antenna and locate a position where
there is optimum GSM signal. Remove
the adhesive cover at the back of the
antenna and mount.
Keep the antenna away from the
microphone
