FCC STATEMENT

The interrogator generates low-level radio frequency energy. The unit has been

tested and found to comply with the limits and specifications as set forth in Part 15 of the

FCC rules. If this unit is suspected of interfering with radio or television reception,

verify that the unit is indeed the source of the interference. First, remove power form the

devices. If the interference continues, then the unit is not the source of the interference.

If the interference stops upon power-down of the unit, then reapply power to the

interrogator. If the interference begins again, proceed as follows:

• Reorient the receiving antenna on the unit experiencing interference.

• Move the interrogator farther from the unit experiencing interference.

• Change the orientation of the interrogator antenna.

If necessary, contact the manufacturer for additional suggestions.

Any changes or modifications not expressly approved by Donnelly Electronics

Inc. may void the users authority to operate the equipment.

This device complies with Part 15 of the FCC Rules. Operation is subject to the

following two conditions: (1) This device may not cause harmful interference, and (2)

this device must accept any interference received, including interference that may cause

undesired operation.

QUICK START INSTRUCTIONS

Immediately upon unpacking the interrogator, verify that you have received the

following items:

BATTERY CHARGER

For units to be used in the US and Canada, this unit is Elpac model

WP1224. The input voltage is 100 to 120 volt 47-63hz. If your electrical service differs

from these specifications, do not attempt to charge the batteries and contact the supplier

of this interrogator immediately for an exchange.

INTERROGATOR HANDLE

This unit consists of two pieces: The armrest, and bottom leg.

ANTENNA

This unit is a white circular disk, eleven inches in diameter. It will be

connected to the bottom leg of the interrogator handle.

INTERROGATOR ELECTRONICS BOX

This unit is a rectangular box attached to the armrest section of the

interrogator handle.

Depress the POWER

ELECTRONICS BOX. The unit should emit a single ‘beep’ and the green POWER

switch on the rear panel of the INTERROGATOR

LED should be illuminated steadily. If the LED is flashing, you should immediately

charge the batteries.

To charge the batteries, plug the power supply that was shipped with the

interrogator into a 120 vac wall outlet. Insert the plug from the charger into the jack on

the rear panel of the INTERROGATOR ELECTRONICS BOX. This jack is labeled

‘CHARGER’. The yellow LED labeled ‘CHARGE’ on the front panel will now be

illuminated. If the batteries are severely discharged, the Yellow LED may blink for

several hours while the charging circuitry is conditioning the batteries. Once the

conditioning has terminated, the Yellow LED will emit a steady glow. When the

charging cycle has been completed, the LED will extinguish.

To verify interrogator operation as a stand-alone unit, it is not necessary to have

the transceiver in operation. No meaningful data will be obtained from this operation, but

it is instructive to test out the operation of the transensors and interrogator. The

following paragraphs will explain how to operate the interrogator:

Depress the ‘POWER’ switch located on the rear of the electronics box to enable

interrogator operation. You will hear a single “beep” tone from the interrogator when the

switch is depressed and the self –test operation has been successfully completed. The

GREEN LED labeled ‘POWER’ will illuminate. The interrogator is now operating

normally, and is continually scanning for a transensor.

Since the interrogator is only a portion of a system, it is necessary to have all the

other parts of the system operational in order to get meaningful data from the

interrogator. One can test the interrogator’s operation without the other components of

the system by placing a transensor near to the antenna. When the interrogator powers up

the transensor, the identification code of the transensor is sent to the interrogator, and

BOTH the ‘ACTIVE’ and ‘INACTIVE’ LEDs will turn on. The interrogator will emit a

single “beep” to indicate that the transensor has been read. Both LED’s will remain on

for about 2 seconds and then go off. This operation is the same regardless of whether a

sensor is connected to the transensor or not.
