10. Preformance test
10-1 Check when Power is Switched On
Before turning on the power switch, check if the power cord is plugged in and the fuse is in place. Also, check for damage to the printed
circuit board, connectors and power section. Make sure that the connections of exchange and stations are completed.
Turn on the Power switch of the exchange.
The front-mounted AC indicator of the exchange comes on. If it does not come on, set the power switch to OFF and check both the
cord and fuse.
Connect batteries after confirming that the system operates on AC mains. Use 2 batteries for the EX-610 and 3 batteries for the EX-620/
630: voltage; 24V, capacity; 3.5 Ah per battery for EX-610/620, 6A per battery for EX-630.
With batteries connected, system unit automatically switches to battery operation when AC power source is cut off. In the event of the
DS-610, DC indicator lamp will be on being accompanied by buzzer. To stop the buzzer, push the buzzer reset switch.
In the event of the DS-620/630, an operation indicator lamp changes from green to red.
10-2 Speech and Function Tests
After completion of wiring, exchange checks and power supplying,
perform operation and function tests from each station. Record the
test results in "Initial Checking Sheet for CP-66".
1. Speech Test
Under the normal condition, make conversation using the
stations connected to the exchange and check the sound volume
and sound quality.
According to the operation environment (surrounding noise,
echo, installed location, etc.), the microphone sensitivity or
speaker volume needs to be adjusted for hands-free conversation.
When the paging function is employed, adjust the gain of the
paging amplifier or change the installed location of the speakers
and stations to minimize feed-back.
Noisy area
Quiet area
Station A
Station B
Voice from station B is
interrupted.
Background noise level
at station A is high.
(Voice from station B is
almost impossible to
hear.)
<Method of Speech test>
(1) Hands-free conversation
1. Call the other station.
2. Start conversation about 50 cm away from each station to check
the sound quality and its volume.
3. Confirm that the automatic voice switching allows for smooth
conversation.
4. When the other station is in a very noisy area, the voice switches
are liable to fail to work properly, causing the voice from the
station in a quiet area to be interrupted. In this case, adjust
microphone sensitivity and speaker sound volume according to
the operating instructions contained in a package of each station.
(2) Conversation between a handset station and handsfree station
1. Call the other station.
2. Start conversation and check the sound quality and sound
volume. Also confirm that simultaneous conversation is possible.
3. When feedback occurs, adjust the microphone sensitivity or
speaker volume of the hands-free station.
