SRG-4500 User Guide (v7.0) Front Panel Menu System • 89
 Option Update Keys are in the form of a 12-character string. Each key is completely unique to a specified option
in a particular SRG-4500. Keys will not work for other options on the same SRG-4500, nor on any other
SRG-4500. Remember to store these keys in a safe place - you may need to re-enter them if a system error
necessitates a system re-configuration.
Key
Every time the SRG-4500 is powered on, this entry displays a pseudo-randomly generated 13-character key. This
menu item cannot be changed by the user. This key is unique to each SRG-4500 and should be quoted when
requesting any additional Option Enable Keys.
GPS Update, NTP Update
These menu lines allow the user to input the supplied Option Update Key(s) in order to enable the related option(s).
Updates can be performed “live” - there is no requirement to re-boot or re-power the unit after key entry.
These menu lines will contain non-zero entries. These will be factory default values, and will be confirmed by the
“:” between the character groups. For valid keys, the character groups will be separated by “-”.
The Timeable Black (TB) Option is always enabled, is not changeable, and will always contain character groups
separated by “-”.
These menu options are always set to “No” upon entry - it requires a conscious action on the part of the user to set
the option to “Yes” and thereby enable Option Update Key editing.
To enter an Option Update Key
1. Highlight the line for which you have a key
2. Press the rotary control. The cursor moves to the word “No”.
3. Rotate the rotary control to select “Yes”,
4. Press the rotary control. The cursor highlights the first character pair of the key.
5. Rotate the rotary control to select the desired character pair.
6. Confirm your selection by pressing the rotary control. The cursor moves to the next character pair.
7. Repeat through all 6 character pairs until you get back to the highlighted line.
8. When completed correctly, the separators between the character groups change from “:” to “-” to indicate that a
valid key has been entered.
9. Exit properly from the menu system to permanently save your new settings. Your enabled option(s) should now
be operational.

For the GPS and NTP systems, a power cycle may be required to fully complete the Option Update process
