FIGURE 2A: TOP VIEW
FIGURE 2B: BOTTOM VIEW

8
RINGER/MESSAGE WAITING INDICATOR
Located at the top right hand side of the telephone above the display, the red lense contains two
different indicators; their functions are as follows:
1. Ring Indicator Flashes when the telephone rings with an incoming call.
2. PABX Message Waiting Indicator Illuminates when a message iswaiting in your PABX voicemail
system (depends on system compatibility). The built-in
message waiting option suits any neon type (minimum
80 VDC) message waiting system and polarity reversal
message waiting (other system types are available as optional
extras). To determine which PABX type your IQ335 has been
prepared to suit, check the telephone’s underside for a label
indicating that specific circuitry has been installed in your unit.
If in doubt, contact Interquartz for further details. To retrieve
your message, consult your voice mail system user guide.
IQ335 is also fitted with a message waiting indicator which is compatible with the voicemail features of
Centrex networks (e.g. Telstra Customnet) and residential line voicemail systems (e.g. Telstra Home
Messages 101 and MessageBank). There are indicators located in the CALLS Key and the display for
these services and are described elsewhere in this manual.
RINGER VOLUME SWITCH
The three available positions allow selection Off (no sound), Low volume, and High volume of the
telephone ringing sound during an incoming call (Figure 2B).
RINGER PITCH CONTROL
The pitch of the ringing sound may be altered by rotating the control to suit your preference to achieve
a distinctive sound, or one that is audible, more distinctive or more pleasant.
ALPHA-NUMERIC KEYPAD
In addition to normal dialing, the alphabetic characters are provided on the keys to enter names in the
Direct Access and Directory memories as well as any online applications that require alphabetic
keystrokes.
RESET BUTTON
Press to restore normal operation of the telephone in case of a malfunction or lock-up. The memories
will not be erased when this button is pressed.
The RESET button should also be pressed when the Memory Protect Switch (illustrated) is moved to a
new setting.

9
CRADLE SWITCH
Located in the handset cradle, this plastic lever is depressed by the handset (when placed in the cradle)
to cut off the line. Note: Depressing this cradle lever too briefly when intending to terminate a call may
result in an accidental “hookflash” that will inadvertently place the call on hold - this is known as “phantom
calls” because the held call may ring again at your extension within a few minutes (the other party will
have hung up, so it will seem as if you were called by a phantom, hence the name “phantom calls”). If
you experience this problem, when terminating your call please depress the cradle lever a little longer
before making/receiving your next call (i.e. phantom calls are not a system or telephone fault).
VOLUME and VOLUME KEYS
Used to adjust the hearing level of the handset earpiece, the handsfree speaker and the headset. To
adjust the volume, press the VOL+ ( ) and Vol- ( ) buttons located under the display (see Figure 2A).

transfer which may be available in your network. It is sometimes referred to as the “Flash” key or
“Facility” key. To learn how to use it, please consult your telephone host system manual. Recall timing
is preset to 100ms. The Recall timing setting affects the Recall key’s ability to function correctly with
your system (see the Installation section regarding this setting).
REDIAL KEY

the speaker, and the indicator will switch on to provide confirmation. Dialing and speech can then
commence. Pressing the key again will terminate the call. The Handsfree state is storable in the Direct
Access memory keys – please see the MEMORY OPERATION section.
The Handsfree mode will be disabled if a headset is connected to the headset jack.
Incoming calls using Handsfree
1. Telephone rings
2. Press HANDSFREE/HEADSET
3. Commence your handsfree conversation.
Outgoing calls using Handsfree (manual or memory dialing)
1. Press HANDSFREE/HEADSET
2. Dial required number or press desired memory key
3. Speak as necessary.
Changing from Handsfree to Handset during a call
Lift Handset and resume your conversation; the handsfree function will switch off automatically.
Changing from Handset to Handsfree during a call
1. Press HANDSFREE/HEADSET
2. Replace Handset
3. Resume your conversation in Handsfree mode.
HINTS FOR HANDSFREE OPERATION
As a courtesy, tell the other party that you are using the handsfree function. He/She may or may not
want people other than you to hear the conversation. A quiet environment ensures best handsfree
performance. When handsfree is used in a noisy room or near a noise generating device (for example,
a TV set), all or part of the message may be interrupted and cannot be heard. To eliminate this problem,
try to lower the noise level in the room.
During the handsfree conversation, your telephone will give priority to the person who speaks louder
when both people are talking simultaneously. Speak ONLY after the other person pauses or stops.
If the other person complains about poor transmission, talk directly at your telephone and from a closer
distance as necessary, or lower volume control.
If the operation of the handsfree feature is not correct, refer to the FAILURE TO OPERATE section.

14
5. HEADSET OPERATION
The IQ335 can be configured to suit many different headsets - please consult the INSTALLATION
section for details to get the best performance from your headset.

2. Quickly press HANDSFREE/HEADSET and the indicator will illuminate
3. The trainee may continue the conversation with the supervisor only listening to the call.
Silent Ringing
Designed for call centres or any application where call-related noise is to be kept to a minimum, this
feature allows incoming calls to ring silently; the operator is aware of the incoming call, but the telephone
does not add to the room noise even when ringing.
To use the telephone in Silent Ringing mode:
1. Set the Ringer Volume switch to the Off position (signified by the square symbol without a bell
symbol inside it)
