Lower

limit

of

frequency

to

be

ignored

after

detection

of

calling

signals

(Ci)

At

the

start

of

reception,

if

the

equipment

detects

the

frequency

of

calling

signals

(Ci)

specified

by

selectors

1

through

4

of

WSW14,

it

will

start

the

ringer

sounding.

When

doing

so,

the

equipment

may

fail

to

detect

the

calling

signals

normally

due

to

noises

superimposed

at

the

time

of

reception.

To

prevent

it,

use

selectors

6

through

8

of

WSW36.

If

the

equipment

detects

higher

frequencies

than

the

lower

limit

specified

by

these

selectors,

it

will

regard

them

as

noise

and

interpret

that

detecting

state

as

being

normal,

allowing

the

ringer

to

keep

sounding

(until

the

equipment

starts

automatic

reception

of

FAX

data

if

in

the

FAX

mode

or

enters

the

TAD

mode

if

set

in

the

TEL

mode,

according

to

the

preset

number

of

ringers).
