Toshiba DKT2004-CT 사용자 설명서

All rechargeable nickel cadmium batteries can develop a “memory” (reduced charge 
capacity) caused by repeated charge and discharge cycles. Batteries that have 
developed this effect do not operate to their fullest capacity.

➤

To avoid memory effect, operate the unit until the battery pack is completely 
discharged before recharging. For example, use the handset off the base all day. 
Only replace the handset on the base at night after a full day of use. Do not “top 
off” the charge after using the battery for a short time.

➤

To erase memory effect, operate the unit until the battery pack is completely 
discharged, then recharge it fully. Repeat this process at least three times.

When the battery pack in the handset is low and needs to be charged you see 

 and the handset beeps. 

To restore your battery capacity, return the handset to the base unit for charging or 
replace the handset battery pack with another charged one.

The optional headset provides a hands-free option for the cordless 
digital telephone. Only use headsets especially designed or 
modified for use with radio frequency equipment. With the 
headset installed, you can use the belt clip to carry the handset and 
converse through the headset.

➤

Open the cover over the headset jack and plug in the headset. 
All feature operations are the same as with the handset. When 
using the headset, the handset earphone and microphone are 
disconnected.

Only the TALK key operates.

None of the keys operate.

Handset beeps once every three seconds.

Handset beeps once.
