BARNETT ENGINEERING LTD. ProTalk Cv2
2.3 Indicators
The Cv2 has four LED indicators to show the operation of the unit and to assist in
troubleshooting.
When the Cv2 is initially powered up, the four LEDs will do the following:
C All will turn on for approximately one second.
C Hook will flash on and off for one second then go out.
C Tone will flash on and off for one second then go out.
C Voice will flash on and off for one second then go out.
C Alarm will flash on and off for one second then go out.
C Hook On power-up, following the initial flashing of each LED, Hook flashes until
the Cv2 has found cellular service. Once the unit has logged onto the cellular
network, the Hook indicator goes out. Hook also flashes while a call is being
placed. After the call has been processed, Hook is on steady until the end of
the call when it goes out.
C Tone Tone blinks once for each DTMF digit that is either received or transmitted.
C Voice Voice is on when the Cv2 is speaking. On power-up, following the initial
flashing of each LED, it will go on continuously for 2 seconds if any section of
the stored database, voice or vocabulary memory is corrupt. If this occurs, the
configuration should be downloaded into the unit and the voice recordings
checked for validity. Voice flashes briefly every second to indicate that the
Cv2 is operating correctly.
C Alarm If an unacknowledged alarm is present, the alarm indicator will flash. When the
alarm is acknowledged, Alarm is on steady. When no alarms are present,
Alarm is off.
2.4 Troubleshooting
Is there power to the unit?
When power is first applied to the Cv2, it will flash the Hook indicator until it establishes
contact with the cellular service. At any other time, the presence of power, and correct
operation, are indicated by the brief flashing of the Voice LED every second.
Does the cell phone work?
Use the local call feature to determine if the unit is working properly. If the call cannot be
completed, query the cell phone to see if it responds - any parameter can be used here. Query
the RSSI (Received Signal Strength Indicator) in the phone to see if there is coverage in the
area. The message “error” will be returned if there is no coverage. This can possibly be
corrected by improving the antenna system.
