# Configuring your RTU Over the Phone

Note: refer to the topic Keycode Programming Guide.

To read or alter configuration settings by phone place a call to the RTU from a touch tone telephone. When the RTU answers, enter any key to start session (unless PINs are configured, then a valid PIN must be entered to start session). Once the session has started, the menu options are repeated.

Keypad # | Menu Options
--- | ---
1 | Acknowledge ALL alarms, enter PROGRAM mode
2 | Enter Read-Only PROGRAM mode (alarms are not acknowledged)
3 | Acknowledge ALL alarms, then report all Unreported and Non-Normal Channels not linked to Destination
4 | Enter SEARCH mode
5 | Repeat the Menu Options
6 | Repeat Unit ID message, Preliminary Report, and Alarm Report
9 | Acknowledge ALL alarms, then report all Unreported and Unacknowledged Channels not linked to Destination

Enter PROGRAM mode by pressing the 1 key on the telephone keypad. The RTU will respond with, "Enter program code."

As with programming at the front panel, for most configuration items, you will have the choice between:

- determining an existing setting
- clearing the setting to factory default value
- establishing a new setting

Note: You may instead enter a "2" which will get you into read-only Program Mode, which as a safety feature only allows you to review, not change, program settings.

Since some of the Front Panel keys are not found on a touch tone keypad, some special conventions apply for OTP (Over the Phone) keystroke interpretation:

Front Panel Key | Keypad Equivalent
--- | ---
ENTER | # # #
POINT | # *
MINUS | # #
CANCEL | # * *

To read existing configuration values:

1. Enter a code at your touch-tone keypad
2. Followed by the # # # key sequence (# # # is the code equating to the ENTER key, when programming over the phone)
3. A voice will enunciate the existing setting or value without changing it.

To clear, erase, or reset a value or setting:

1. Enter the code
2. Followed by the reset delimiter **
3. Then the # # # keys

To change a value or setting:

1. Enter the code
2. Followed by the command delimiter *
3. Add the new value or setting
4. Signal the end of the command string with # # # (the ENTER code).

Note: When you enter a leading #, the RTU does not yet know whether the intention is to enter # # # to indicate an ENTER or a single # as a prelude to something else. Therefore it will respond to the first # with the word "pound" recited back.

Special case: Over the phone, you may not configure more than one consecutive dialing delay because two ## in a row is interpreted as MINUS when configuring.

Note: Some programming items can not be performed over the phone and are only available within Alarmware™.

Note: The action of entering Program Mode automatically acknowledges all unacknowledged alarms, regardless of destination group.
