ON/OFF

The Bi-Way position is switched on by

touching the ON/OFF button. The lamp

indicates when the position is ON.

In normal working conditions no manual

operation is required once the system is

switched on. The volume in both direc-

tions is pre-set per position by screwdriver

adjustments accessible from the rear of the

cabinet.

The three buttons in addition to the

ON/OFF button are included to take care

of special conditions which may

occur during use.

MICROPHONE SELECTOR -

- "Microphone selector" button with

lamp for switching to an optional

goose-neck microphone fitted to the

operator's unit. This enables handsfree

communication even in periods of

intense noise on the operator's side.

STAND-BY

- The "Stand-by" button with lamp to set

the system in listen mode with reduced

volume, reduces the ambient noise from

the public side during waiting periods.

PUSH-TO-TALK

- "Push-to-talk" button to amplify the

operator's voice on the public side,

enables distinct communication

in periods of intense noise, as well

as for attracting people at a distance

from the counter.

It also allows the operator to speak at

normal conversational level to people

with hearing difficulties.

SIMPLEX

- Simplex button. When "Stand-by"

is not selected the "push-to-talk"

button will give normal simplex

operation without extra amplifica-

tion. Active simplex function is

indicated by the corresponding LED.

Screen microphone and loudspeakers

One electret microphone and two loud-

speakers are installed on the public side of

the glass partition. These elements may be

attached to the glass, partly concealed or

completely built into the screen. The stan-

dard microphone kit and loudspeaker kit

contain all materials necessary for mount-

ing on the public side of one Bi-Way posi-

tion.

The microphone and its connecting cables

is concealed in a thin aluminium list

attached to the glass screen by means of

self-adhesive tape. The list can easily be

adapted to glass partitions of all types.

The compact loudspeakers are attached to

the glass on each side of the microphone

list which may terminate in the loudspeak-

ers allowing hidden cabling between the

three elements.

The loudspeakers are also provided with

self-adhesive tape but they may also be

fixed to the frame of the partition, or the

wall, by means of screws.
