What this headset does and who uses it

The Plantronics CS545 XD is a mono wireless headset built for desk-phone users who need to move around the office while staying on calls. It operates on a 900 MHz band and offers up to 350 feet of range from its charging base. The headset supports one-touch answer, end, volume and mute controls so calls can be managed away from the handset. Up to three additional XD Series headsets can be conferenced in for collaboration.

What to verify before ordering

This unit is the 88909-01 model without a handset lifter; if your phone requires mechanical lifting you will need the HL10 accessory sold separately. Confirm that your desk phone has a compatible headset port or electronic hook-switch interface for direct call control. The base connects via standard telephone cabling, so check port availability on your device. Ensure the 900 MHz band is permitted in your region and will not conflict with other wireless systems.

Build, mounting and daily use

The convertible design lets you wear the headset over the head, over the ear or behind the neck to suit long shifts. An extended boom with a noise-canceling microphone filter reduces background sound for clearer transmit audio. Adaptive power management automatically lowers output when the headset is near the base to extend battery life. Hot-swappable battery modules provide unlimited talk time without docking interruptions. Guest headsets can subscribe simply by docking on the base for quick setup.

Questions about this item

Does the Plantronics 88909-01 CS545 XD Mono Wireless Headset include a handset lifter or must it be purchased separately?

The base model 88909-01 ships without a lifter; the variant 88909-01+HL10 includes the HL10 handset lifter in the box.

Should I choose the CS545 XD narrowband or wideband audio mode for my office density?

Narrowband mode extends talk time in extreme density environments; wideband mode delivers clearer conversations when density allows.

What does the 350‑foot range mean when the headset is used at a typical desk distance?

At close range the adaptive power system automatically downshifts to low power, saving battery while maintaining a stable 900 MHz link.
