To connect the headset, open the rub- ber cover marked 
on the side of the handset, then insert the headset’s plug into the jack.
With a headset connected, you can make or answer calls as usual using the speakerphone or the keys on the hand- set.
You can use a handset holder (available at your local RadioShack store) to hang the handset on your belt for greater con- venience.
When you finish using the headset, dis- connect it from the handset and close the rubber cover to protect the jack.

Notes:
•Connecting a headset disconnects the handset’s earpiece and micro- phone, but it does not affect the ET- 687’s speakerphone.
•VOL s or t on the handset also con- trols the connected headset’s vol- ume.
•If you place the handset on the base face down to recharge it while the headset is connected, be sure the handset seats properly.
