1. Ensure that the system is registered with “Iridium” being displayed on the
handset. Check that there is adequate signal strength by observing the
signal “bars” on the display. 5 bars equates to full signal reception.
2. Dial an outgoing call. The phone number format is 00+<country
code>+<local number>. For example, to dial a Sydney Australia number:
0061295601234. (NOTE: If a Telstra Satellite SIM is used, then you may
exclude the leading “0061” for Australian phone numbers, however the
state area code is still required, eg. 0295601234).
3. The handset will display the call is in progress, and will take about 10
seconds to connect. Once answered, verify audio in both directions with
both the handsfree and handset.
4. Have an incoming call placed, and verify ring signal is heard from the
speaker (when handset in cup) and from the handset when it is out of the
cup. Answer the call using the handset button, and verify audio in both
directions.
Volume adjustment
The volume is changed on the speaker and handset simultaneously by using the
up/down keys on the handset.
NOTE: To save the volume setting in between RST625 power
recycling, please perform a power down using the handset power
button, located on the bottom of keypad. This will permanently store
the speaker volume into memory even after system power-off. You
can then turn the system back on with the handset power button, or by
recycling power to the RST625.
When the volume is turned up high, this may increase the level of feedback (echo)
heard from the B-party phone call end. This will vary depending on speaker and
microphone placement, cabin acoustics, etc.
Powering off
The system phone is powered on and off by the panel power switch.
In addition, the system can be put into standby power mode by using the power
button on the bottom of the handset. In standby mode, the transmitter is off and the
system is not registered on the Iridium network. The standby mode consumes about
30mA.
NOTE: If the system is in standby mode, and then power is recycled for
whatever reason, the system will be fully on and will attempt to register.
