INSTALLATION & OPERATION

Choose a suitable location, free from

magnetic or electrical interference for

installation and use of LH160

(1) Install the LH160 onto a panel or

wall under the counter, ensuring that

the cables are securely anchored.

(2) Connect the loop antenna (optional

accessory) or other compatible loop

coil to the loop output terminals. For

optimal performance the loop antenna

or coil should be located about 80cm in

ftront of the customer.

Press the tab above the connector

terminal and release after inserting the

wire of the loop antenna or coil. Polarity

is not important.

(3) Connect a compatible Geemarc

Microphone to the Mic1 jack.

(4) If required connect a second

compatible Microphone or Aux input to

the Mic2/Aux jack. Use the switch to

select the type of input.

(5) Using a small common blade flat

screwdriver, turn the Mic1, Mic2/Aux,

Tone and Field Strength controls fully

anti-clockwise (to their minimum levels).

(6) Select the power source (car battery

or mains AC adaptor) and connect the

car adaptor cable or AC power adaptor

to the power input socket.

(7) Switch on the external power and

check that the Power ON LED

illuminates

(8) Apply the input signal (for example

speaking into the Mic) to Mic1 or

Mic2/Aux and turn the corresponding

control clockwise until the

corresponding LED begins to light up.

(9) Repeat the above for the second

input if used. While setting up, apply

only one input at a time.

(10) While the input signal is present,

adjust the Loop Current adjustment

control clockwise to get the desired

loop output level. The Loop Current

Indication LED will become brighter as

the Loop current is increased

(11) Test the performance of the

system using a field strength meter.

Adjust the Tone and Loop Current

controls to achieve the desired

performance. The Tone adjustment

enables compensation for loss of

higher frequency signal during

transmission.

motor vehicle please contact Geemarc
