Step 2
Have a call placed to the mobile and confirm
proper operation. Use both the handset and
the optional hands-free during this call if the
phone is so equipped.
Step 3
If you experience difficulty placing and
receiving calls, check the voltage standing
wave ratio (VSWR) using the following
method. Measure the power output of the
radio with the radio connected to the vehicle
antenna through a directional watt meter.
Measure the forward power and reflected
power with the watt meter and compute the
VSWR as follows:
The VSWR should be less than 2:1. If the
VSWR is greater than 2, check the antenna
and its cable connector.
Checking Auxiliary Alert Feature
Step 1
Prepare the unit to receive test calls by
enabling the auxiliary alert feature, in
accordance with the procedures provided in
the User Manual. Place a test call to the
mobile.
voltage standing wave ratio =
where R = reflected power
forward power
1+R
1 - R
