Adjustment of the VP1002
The adjustment consists of 2 steps.
1. Tuning the antenna
2. Set the antenna power level
Step 1 : Tuning the antenna
The antenna must be ON for tuning. Check the ANT ON led, blue is OK. If not, set the connected V-
pack in “id” mode, see manual of the concerning V-pack. Tuning is done with LT on the antenna, see
manual of the concerning antenna.
Tuning sequence :
-
Set the power of the connected V-pack to 50, see manual of the concerning V-pack.
-
Adjust now with Lt of the antenna until the “TUNING” led on the VP1002 is green.
Step 2 : Set the antenna power level
The maximum power is set at the connected V-pack. See the manual of the V-pack for details about
adjusting the power.
If power level is set to high at the connected V-pack the power limiter will be activated. The led PWR
LIMIT will be on. After a delay of approximately five seconds ithe VP1002 restarts. If nothing has
changed the safety circuit is triggered again until the transmitted powerlevel is lowered.
How to set the correct power level :
-
Set power level AP at maximum 99.
-
If the PWR LIMIT led is OF and the green TUNING led ON the adjustment is OK.
-
If the PWR LIMIT led is ON (means safety circuit activated) the power must be lowered. Set
the power level to 90 instead of 99 and check again. If this has no result, lower the power
level to 80 etc.
Final check
Switch the power to the connected V-pack of and after 10 seconds on again. All red leds should be
switched off.
