Customize Your Headset

Your headset comes configured for your right ear with a pre-installed small eartip and medium earloop. You can also configure your headset for your left ear, install a different sized eartip and earloop, or install the headband.

Change Headset Configuration

1. Gently pull the eartip from the headset. Rotate the earloop down 90°.

NOTE You will feel resistance when rotating the earloop down; this is normal.

2. Remove the earloop from the headset.

3. To wear the headset on the right ear but with a different size earloop or eartip, select the size you want and reinstall in reverse order as shown. Be sure notch in the eartip faces the microphone.

Left Earloop Assembly

1. Choose the size of earloop that fits most comfortably. Align the earloop as shown and insert it onto the headset. Be sure the earloop is flat against the headset and rotate the earloop up 90°.

2. Choose the size of eartip that fits most comfortably. Align the eartip with the notch facing the microphone as shown. Press on to attach.

Headband Assembly

The headset can be rotated for wearing on the left or right ear.

NOTE Before installing the headband, remove the eartip and earloop from the headset.

1. Hold the headband so it is aligned to receive the headset as shown and insert the headset into the headband.

2. Rotate the headset up.

3. To optimize the position of the headset, push the headset in so the microphone is close to the corner of your mouth.

Position Your Headset

When you wear the headset, the microphone should rest as close to your cheek as possible without touching. The microphone can be adjusted inward by the pivoting earpiece to optimize the position of the headset.

1. Slide the headset over and behind your ear and fit the eartip into your ear.

2. Holding the base of the headset, push it in and back towards your ear to allow the pivoting earpiece to bring the microphone close to your mouth. As the base of the headset moves backwards, you will feel soft clicks until the microphone rests close to your cheek.

Connect Your Desk Phone

This section describes how to connect the base to your desk phone.

Connect the Power

Plug one end of the power supply into the power jack on the back of the base and the other end into a working power outlet. The Power On LED will be solid white.

Charge the Headset

Your Base

Base Phone Button and Switches

1. Subscription Button

The headset and base that came in the box are subscribed (connected) to each other. However, if you wish to use a new headset or need to restore subscription to your current headset, the units can be subscribed to each other by the following two methods.

Automatic Secure Subscription

With your system idle, docking a headset will automatically subscribe it to the base, making it the primary headset. The Power On/Subscription LED will flash white during subscription process and become solid white when the new subscription is established.

Manual Over-the-Air Subscription

1. With your system idle and your headset undocked, press and hold the subscription button on the base for three seconds. The Power on/subscription light will flash white.
2. Press and hold the volume up button on the headset for three seconds until the headset LED turns solid white. When the Power on/subscription LED on the base becomes solid white, the headset and base are subscribed to one another.

NOTE If the subscription process times out after two minutes or if the subscription process fails, the subscription LED on the base will go dark for three seconds and then re-illuminate steadily to indicate power is applied to the base. If this occurs, try to re-subscribe the headset again.

Ending Subscription

If the base is in subscription mode and you want to stop the base from searching for a headset, press the subscription button again. The subscription LED on the base will go dark for three seconds and then re-illuminate steadily to indicate power is applied to the base.

Power On/Subscription LED

Base Status	Power On/Subscription LED
Primary headset subscription	Flashes white
Primary headset subscribed to base	Solid white
Conference call headset subscription	Flashes white
Active conference call with guest headsets	Flashes white

2. Wideband/Narrowband Audio Switch

The CS540 has wideband audio, which allows speech to sound clearer and more natural. If your desk phone is capable of wideband audio, set the Wideband-Narrowband audio switch to yellow for wideband.

NOTE: Talk time will be reduced when operating in wideband mode.

Set the switch to black (narrowband) for longer headset battery life or to increase the number of systems that can work in a small area.

3. Auto Answer Switch

Auto answer saves a button press to establish the radio link between headset and base. When auto answer is set to black you must press the headset call control button to answer an incoming call.

When Auto Answer is set to gray you can answer a call just by lifting headset from the base.

NOTE Auto answer/end capability requires the use of an EHS cable or HL10 lifter. Visit plantronics.com/accessories for more information.

Conference Up to Three Additional Headsets

You can conference up to three additional headsets to a call in progress.

Join a Conference Call

While in an active link between the primary headset and the base (on a call), place the guest headset into the primary user's charge cradle (this connects the headset to the base). The base subscription LED will begin flashing. After a few moments, the primary user will hear a triple tone in their headset indicating the guest headset wishes to join the call. Within ten seconds of hearing the triple tone, press the primary headset's call button to accept the guest headset. If the process fails or times out because the button was not pressed within ten seconds the guest subscription is terminated and the guest will hear an error tone in their headset.

To connect a guest headset that is of different variety than the primary headset press the base subscription button while the base has an active link. Next, press the guest headset volume up button until the indicator light turns on. The base subscription LED will begin flashing and the primary user will hear a triple tone in their headset indicating the guest headset wishes to join the call. Within ten seconds of hearing the triple tone, press the primary headset's call button to accept the guest headset. If the process fails or times out because the button was not pressed within ten seconds the guest subscription is terminated and the guest will hear an error tone in their headset.

NOTE Headsets in a conference maintain independent mute controls. The base only indicates the primary user's mute state.

Exit a Conference Call

Guests headsets can remain as guests through multiple calls. To remove a guest headset, press the guest headset's call control button or dock the primary user's headset in the charge cradle. A single tone in the master headset will be heard as each guest leaves the call.

NOTE The user of the primary headset in a multiple headset conference scenario may hear additional tones (triple tones) in their headset and see the subscription LED on the base flash as guest headsets join the call. These additional tones and flashing LED indicate that the guest headset has a different version of firmware than the primary headset, but can still be used for conferencing.
