Howto:Upgrade DECT handset firmware
Applies To
This information applies to
- IP52
- IP54
More Information
Problem Details
The software PCS 6Rc can only be loaded into IP52/54 handsets already equipped with PCS 6Ea. If the handset has an older firmware (e.g. v5) than it must be temporarily updated to the PCS 6Ea firmware. A direct upload of the new PCS 6Rc build on v5 firmware will destroy the handset.
Use the *99984* service code to determine the firmware number.
Installation
Procedure for upgrade from V5 into 6Rc
- upload version 6EA
- Send a default to handset
- Upload version 6Rc
- Send default to handset
Known Problems
BUT - after upgrade from version 5 into 6(x) you might experience acoustical problems as in between the version 5 - to 6 Kirk has implemented a new type of loudspeaker which will give you a higher sound preassure. Should the acustical conditions be adjusted the handset must be run through a final test for adjustment of the acoustical parameters.
