Samsung iDCS100 System Administration Guide6To clear the DISA alarm:1. Lift the handset and dial the access code 58.2. Enter the DISA alarm passcode (‘5678’ by default—refer to MMC 202).3. Replace the handset.WARNINGAs it is impossible to prevent unauthorised access to your telephone system by hackers,we suggest that you do not turn the DISA feature on unless you intend to use it. If you douse this feature, it is good practice to frequently change access passcodes and periodi-cally review your telephone records for unauthorised use.ACCOUNT CODESAccount codes are used to charge an outside call from a station to a specific account.These account codes can be either forced or optional (voluntary). If forced, a messageis displayed at a station that the code must be entered when the station user attemptsto make an outside call.FORCED ACCOUNT CODESForced codes may be verified or unverified.• If verified, the entered code is checked against a system list of up to 500 entries.Codes can include digits 0–9.• If unverified, the entered code is not checked against the system list.

Lift the handset and press the ACCT key or ACCT soft key or dial 47.2. Enter the account code.If a correct code is entered, you will hear dial tone and you can make an outside call inthe usual manner.
