from the socket on the left of the test board. Plu the
cable leadin to this stae’s servo in its place.
HELP!
If the LEDs flash rapidly when
you run the test at Step 14, you
have a faulty connection.
Double-check the servo cable’s
connection to the socket on the
test board, TURNING THE
POWER PACK OFF BEFORE
YOU DO. If the liht still flashes,
carefully unscrew the servo
housin and check that the
internal connector plu is in
place. If you pressed the wron
button, reset the board by
holdin down the TEST/SET
switch for several seconds.
9The shaft at the top of the servo casin should rotate 45 derees to the left,
stop, then move back across to 45 derees to the riht. After you have run
the test, turn o the power switch on the battery pack.
TESTING THE SERVO
7Turn the test board to ON. All the LEDs should blink
twice, then turn o to leave only number 1 lit.
8Now press the TEST/SET switch
briefly to run the servo test.

10 Re-familiarise yourself with the lihts and switches on the test board, which you
have used to set the servos’ ID numbers. Each time you press the UP switch, the ID
number increases by one, and the result is displayed by the two banks of LED
lihts. The top row reads in tens and the bottom in units. For example, to set the ID
to 21, press UP 20 times. This will liht up the 20 LED and the 1 LED. (If you
overshoot, press the DOWN switch to take it down one step at a time.) When the
ID number is correct, you set it by pressin and holdin the TEST/SET switch.
