operator may change frequency and the coupler will not tune. It may

eventually burn coils and/or relays.

2. Reset function is convenient to force a reset in situations where a

coupler will not retune. For example, the last tune achieved on 14.100

with VSWR 1:1.7, the coupler is instructed not to retune until it

reaches 1:2.0 - If the coupler is reset and therefore will retune at your

next transmission it may tune to 1:1.1 or much better before the last

read of 1:1.7 - reset can also be used to listen to other frequencies out

of band of your last setting in a broad band mode, and therefore in-

creasing your incoming receive level by several “S” units. Reset is

also accomplished by turning power off and on again.

6.1 Tune, Tune Lock/Reset

Tuned (green LED)

Turns on when the coupler has successfully tuned.

Normal/Tune Lock

Toggle switch which allows user to prevent coupler re-tuning by

switching to the Tune Lock position. When in the Tune Lock position,

the red LED blinks to notify the user that the coupler is locked on the

current setting.

Reset

Pushing the red reset button allows the coupler to be reset, if the tog-

gle switch is in the normal position. This is preferred over turning the

input power off and on.

6.2 SmartLock Notes

The Tune Lock function is in most cases unneeded. Inadvertent retun-

ing is a rare occurrence. Retuning may occur when the environment or

antenna system has changed. In this case, retuning is within normal

operation of the coupler.
