Operation

 

Functional

 

Test

 

Turn

 

the

 

receiver

 

on

 

and

 

check

 

that:

 

1.

 

The

 

Indicating

 

LED

 

is

 

ON

 

and

 

Red.

 

2.

 

The

 

Low

 

Battery

 

LED

 

is

 

OFF.

  

If

 

either

 

of

 

these

 

conditions

 

does

 

not

 

exist,

 

replace

 

the

 

battery

 

Plug

 

the

 

transmitter

 

into

 

a

 

live

 

socket

 

and

 

move

 

the

 

receiver

 

scanning

 

head

 

over

 

the

 

face

 

of

 

the

 

transmitter.

 

The

 

frequency

 

of

 

the

 

beeping

 

should

 

become

 

very

 

rapid

 

or

 

change

 

to

 

a

 

continuous

 

tone.

 

The

 

Indicating

 

LED

 

should

 

turn

 

Green

 

when

 

the

 

scanning

 

head

 

is

 

detecting

 

a

 

signal

 

”hotspot”

 

(this

 

is

 

good

 

practice

 

for

 

scanning

 

since

 

the

 

indication

 

is

 

similar

 

to

 

finding

 

the

 

correct

 

circuit

 

breaker

 

at

 

the

 

panel.)
