QUICK START
1. Fit CLD1-AC to a panel or wall under the counter, away from contact by the
system user. Ensure the cables are positioned such that they are not vulnerable
to damage and are unlikely to be snagged or disconnected from the unit.
2. Fit either the loop coil (provided) or perimeter loop:
·
Unfold the loop coil and fit vertically inside the front panel of the counter
using the adhesive fixings provided. The top of the loop coil should ideally
be at a height of 800mm above the floor.

If a perimeter loop is to be used, the feed wires to the amplifier should
be twisted together. See 'Designing Induction Loops handbook' for details.
3. Connect the loop wires to 'LOOP OUTPUT' terminals. Polarity is not important.
To open the spring clamp terminal - insert a flat bladed screwdriver into the
small “tab” above the hole. Push gently until hole opens.
4. Connect signal to 'INPUTS 1 and 2' as required
(see:
Connection details
)
.
5. Position 'INPUT 2 SELECT' slide switch for Line or Mic as required.
6. Connect AC power cable to 'POWER INPUT' socket on the unit. Connect to AC
supply.
7. Switch on external AC power: Check green 'POWER' LED illuminates.
8. Apply input signal (e.g. by speaking into mic') and if required increase
corresponding 'INPUT 1 or 2' control until the green 'INPUT SIGNAL' LED
begins to light.
9. Repeat item 9 for the second input (if used).
Only apply one audio signal at a
time when setting up the system.
10. If required adjust the 'LOOP CURRENT' control until the yellow 'LOOP
CURRENT' LED lights at peaks in the input signal.
11. Test the performance of the system using a loop receiver or field strength
meter and adjust 'MLC' & 'LOOP CURRENT' to achieve acceptable
performance.
Note: Once the 'LOOP CURRENT' control is set, do not adjust it again.
