Trouble Shooting
POWER
When the WaveWare Paging Transmitter Unit is assembled and power is applied, you should be able to see
a red Power indicator illuminated on the side of the Transmitter Unit. If not, verify that all connections are
tight and verify that 110 VAC power is available at the power outlet. If connections are tight, power is
available and the red Power indicator doesn’t illuminate, determine if the Power Adapter is at fault by
trying another Power Adapter. If the Transmitter Unit still does not respond, the Transmitter Unit is most
likely in need of repair or replacement.
At power-up, the Transmitter Unit is supposed to send a status message through the serial port to the host
PC.
PAGERS
When you send a paging message command to the Transmitter unit from the PC, the green RF TX
indicator on the Transmitter Unit should illuminate for a few seconds to indicate that transmission is
occurring. If you don’t receive a message on the selected paging receiver, follow the checklist below to
troubleshoot paging reception:
1.
Pager turned on
2.
Pager has fresh battery
3.
Pager properly defined in the paging control application software on the host PC.
4.
Pager located at least arms length away from Transmitter Unit during transmission. (Some paging
receivers do not properly decode paging messages when the paging receivers are located in close
proximity to the transmitter antenna. Holding a paging receiver at arms length away from a transmitter
antenna is usually sufficient to allow the paging receiver to properly decode a paging transmission).
5.
Antenna attached to Transmitter Unit
6.
Pager at the same frequency as the Paging System
7.
Pager uses POCSAG paging protocol
CARRIER DETECT
The Carrier Detection signal is indicated by the green RF CD indicator on the side of the Transmitter Unit.
When a carrier signal is detected, and the Carrier Detect mode of operation is enabled, the paging system
will delay transmission until the detected carrier signal disappears. If the Carrier Detect operating mode is
enabled in the paging system, and you find that paging transmissions are delayed for significant periods of
time due to interference on the channel, you should temporarily inactivate the Carrier Detect mode to allow
transmissions to occur regardless of other transmissions on the channel. You may find that you get
excellent paging reception even with Carrier Detect inactivated. You may want to contact your nearest
FCC field office to find out what is causing the unwanted interference on your channel. Please note that
the typical
WaveWare Paging System
installation uses a 2 watt system that operates subservient to other
operators on the same frequency. If you find that the unwanted transmissions are legal, and if you find that
your paging reception is suffering due to the unwanted transmissions from another source, you may have to
change your paging system to another operating frequency. A frequency change is a costly process and
should be avoided.
If you have multiple
WaveWare Paging System
s installed in the same facility, and at the same operating
frequency, you should activate the Carrier Detect mode on all paging systems in order to ensure paging
messages are being properly transmitted to paging receivers.
