Pager interference

Restaurant Pagers Going Off Randomly? Change the System ID

If your pagers buzz when nobody at your stand pressed anything, either your own system sent an all-page, or a nearby system (often the shop next door with the same brand) is on the same ID. Two minutes of checks tell you which.

Find the cause in four checks

  1. 1

    Is every pager going off, or just some?

    All of them, playing a tune or vibrating non-stop, is usually an alert from your own system (out-of-range or locate), not interference.

  2. 2

    Rule out your own all-page code

    JTECH IQ systems page every pager off the charger with 1249 SEND, and Retekess T112 keypads silence all pagers with a long-press of 9. A staff member pressing the wrong code is the commonest "random" page.

  3. 3

    Note when it happens

    Pages that line up with the neighbour's busy times point to a shared system ID on the same brand.

  4. 4

    Change your system ID

    Give your transmitter and pagers an ID nobody nearby uses. Steps per brand are below. LRS says it sets non-zero system IDs specifically to stop conflicts with other LRS systems nearby.

After changing a system ID, your pagers must be set to the new ID too, or they will stop answering your own transmitter.

LRS TX-7470 / TX-7471 transmitters

Check the current ID first: SETUP, 31337, 1 (System), press F2 seven times to the bottom of the menu and open System ID. Write it down.

  1. 1.Change it

    In that System ID option the number flashes. Type the new number and press Enter, then F4 three times to exit. Station ID appears while scrolling but is something else: keep going to System ID.

  2. 2.Put every pager on the charger

    Then press SETUP, 31337, F2 (DN), 1 (Program), 2 (Prg Vibe), 1 (Guest) and 1 (Coaster) or 2 (Paddle), then F1 or F4 for vibration.

  3. 3.Unplug the charger power supply

    When the pagers stop their wake-up flash, press ENTER straight away (it is timed). They slowly brighten and dim while they take the new ID.

  4. 4.Plug the charger back in and test

    Keep at least a foot between pagers and transmitter. Any that didn't respond: repeat. F4 three times to exit.

LRS Butler XP and battery pagers

Read a pager's system ID by taking its battery out and putting it back: the boot screen shows "C1: [system ID] pager number". The Butler XP's own ID is set in the Butler Configuration Utility.

Retekess TD157

  1. 1.Press CALL and DEL together

    F1 shows. Press 1, then CALL: the current base ID is shown.

  2. 2.Type a new ID

    Then re-pair each pager (F2) so it listens to the new ID.

Retekess TD175 / TD175P

  1. 1.Set, then △ three times to F4

    Press Call, type a keypad ID (1–999), press Call.

Retekess TD177

  1. 1.Settings: E-01 is the system ID

    Change it, then pair each base again: enter the ID on the main screen, press the base's raised button, press F1.

Frequently Asked Questions

Usually one of three things: someone used an all-page or locate code, the pagers are giving an out-of-range alert, or a nearby system of the same brand shares your system ID. Changing the system ID fixes the last one.
It can if both use the same brand and ID. LRS sets non-zero system IDs to stop its systems conflicting with others nearby. Give your system an ID nobody near you uses.
On a TX-7470 or TX-7471: SETUP, 31337, 1 (System), F2 seven times, open System ID, type the new number and press Enter. Then program all the pagers to the new ID with the Prg Vibe option.
No radio is involved. With Bzz, each guest's alert goes to their own phone's browser over mobile data or Wi-Fi, tied to their place in your line, so another venue's system can't reach it.
