VSWR=1+R
1- R
where R=(Pr/Pf)
If the VSWR is greater than 2, check the antenna, cable and
connector. Optimum VSWR is 1.
Step 3. Using the car kit and the personal cellular
telephone, place a call to confirm that it is
operating correctly.
Step 4. Have a call placed to the phone and check the
general operation, such as the Hands-free and
convenience on/off features.
4.2 CHECKING ANTI-SKID BRAKING SYSTEMS
The test procedure is divided into eight different checks in
order to cover various types of interference. Disturbance of
an electronic anti-skid braking system can usually be
detected in several different ways; e.g., the lights, irregular
audible sounds, noticeable changes in the braking system’s
performance, etc.
Check 1. With the car stationary in neutral, the engine
running at fast idle, and your foot off the brake
pedal, make a phone call.
Check 2. Repeat the previous check but with your foot on
the brake pedal.
Check 3. With the car stationary, and with at least several
car lengths of clear area in front of the vehicle,
engage a forward gear. Bring the clutch up to the
biting point whilst preventing forward motion by
applying gentle pressure to the brake pedal. Help
may be required to achieve the above. Make a call
and ensure no malfunctions are observed.
Check 4. With your foot off the brake pedal and driving at
a moderate speed of 15 to 25 mph (24 to 40 km/
hour), have the phone called.
Check 5. With your foot exerting slight pressure on the
brake pedal, enough to turn on the brake lights,
have the phone called.
Check 6. While making moderate deceleration stops from
25 to 30 mph (40 to 48 km/hour), have the phone
called.
Check 7. While making an ‘emergency’ type stop from 20
mph (32 km/hour), have the phone called.
Check 8. If no interference occurs, repeat check 7 doing an
‘emergency’ type stop from 30 mph (48 km/
hour).
CAUTION
Severe disruption of the electronic anti-skid
braking system may cause loss of control of
the vehicle while performing the following
test.
IMPORTANT
If no malfunctions are observed while
performing any of the previous tests, it can be
assumed that no apparent problems exist and the
vehicle can be released to the customer.
However, if any of the tests cause a brake
malfunction, any further tests should be
stopped, and the phone removed from the
vehicle immediately. Then contact the vehicle
