Programming Mode Operation (Setting A New Security Code):
NOTE: # and ∗ are special characters and should not be used in your security
code except for one special case (more on this below).
1. Turn on the unit with Power switch S1; Power LED D9 should light up.
2. Press in the Program button S2; Activity LED D4 should light up.
3. Lift the phone receiver and press # ; you should hear a confirmation tone.
4. Enter the new 4 digit security code; you should hear a confirmation tone
and the Activity LED (D4) should flash on and off until you press the Pro-
gram button again to go back to normal operating mode.
• Avoid using codes that start with common TELCO feature numbers
like 69XX or 72XX as your security code. You may wind up acciden-
tally activating some feature on your phone line! Check your phone
book for local feature codes to keep this from occurring.
• Entering #, #, #, # as the new security code will disable the security
check feature and allow the unit to operate in free running mode. In
this mode the DCI1 will always respond to any valid DTMF tones
without forcing you to enter a security code first.
• If you have any errors during the programming phase, recycle the
unit’s power and start again from step 1.
5. Once back in normal mode (Program button released), the Activity LED
(D4) should stop flashing and you’re ready to go!
