5. Setup
5.1 Initial Charging
Before first use, fully charge all pagers and the keypad transmitter. Place the pagers on the charging base. The pager lights will indicate charging status (flashing while charging, solid when fully charged).
5.2 Pairing Pagers with Keypad
The pagers are typically pre-paired. If re-pairing is needed or for new pagers:
- Press the SETTING button (gear icon) on the keypad to enter setting mode.
- Enter the desired pager number (1-999) using the numeric keypad.
- Pick up the pager from the charging base and press the 'v' (confirm) button on the keypad within 3 seconds. The pager will vibrate/flash to confirm successful pairing.

This graphic demonstrates the straightforward pairing process for the Retekess TD158 system. It shows three steps: pressing the SETTING button, entering the pager number on the keypad, and confirming by picking up the pager from the charging base. Examples of use in a restaurant, hospital, and industrial setting are also depicted.
6. Operating Instructions
6.1 Calling a Pager
- Ensure the pager is powered on and within range.
- Enter the pager number (1-999) on the keypad.
- Press the CALL button (bell icon) to send the alert. The corresponding pager will activate according to its set alert mode.

This four-step diagram illustrates the typical customer flow in a restaurant using the Retekess TD158 system: 1. Customer places order, receives pager. 2. Waiter calls pager when food is ready. 3. Customer's pager alerts (vibrate/flash). 4. Customer returns pager and collects food.
6.2 Setting Alert Duration
The duration of the pager alert can be adjusted from 1 to 250 seconds via the keypad settings.
6.3 Muting Pagers
To mute all pagers, simply press 0 + CALL on the keypad. This will close all active pager alerts without needing to turn off each pager individually.
6.4 Pager Status Indicators
The pagers use light indicators to communicate their status:
- Vibrate + Flash + Beep: Indicates an incoming call.
- Flashing Light: Pager is currently charging.
- Solid Light: Pager charging is complete.

This image explains the meaning of the pager's light indicators. It shows that a combination of vibrate, flash, and beep indicates a call, while a flashing light signifies charging, and a constantly lit light means charging is complete.
6.5 Range and Signal Penetration
The system offers a significant operating range, allowing customers to wait comfortably without missing their call.

7. Maintenance
- Cleaning: Wipe the keypad and pagers with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Battery Care: To prolong battery life, avoid fully discharging the pagers frequently. Charge them regularly.
- Storage: When not in use for extended periods, store the system in a cool, dry place.
