3. Setup

3.1 Battery Installation

The E57 call button is powered by two CR2 batteries, which are typically included. To install or replace batteries:

1. Carefully open the back cover of the call button.
2. Insert the two CR2 batteries, ensuring correct polarity (+/-).
3. Securely close the back cover.

3.2 Pairing with a SINGCALL Receiver

The E57 call button must be paired with a compatible SINGCALL receiver to function. The pairing process typically involves placing the receiver into a pairing mode and then activating the call button.

General Pairing Steps (refer to your receiver's manual for specific instructions):

1. Ensure your SINGCALL receiver is powered on and in close proximity to the E57 button.
2. Activate the pairing mode on your SINGCALL receiver. This usually involves pressing a specific button on the receiver for a few seconds until an indicator light or sound confirms pairing mode.
3. While the receiver is in pairing mode, press the large "CALL" button on the E57 transmitter.
4. The receiver should indicate successful pairing (e.g., a beep, flash, or display update).
5. Test the connection by pressing the E57 button again to ensure the receiver responds.

3.3 Mounting and Placement

The E57 button offers flexible placement options:

• Portable Use: Attach a lanyard (if provided) to wear it around the neck, or simply carry it in a pocket.
• Wall Mounting: The button can be affixed to a wall using adhesive or screws (not included) for fixed locations like bathrooms or beside a bed. Ensure it is placed within the transmission range of the receiver.

4. Operating Instructions

Once the E57 call button is paired with a SINGCALL receiver, operation is straightforward:

1. To send an alert, simply press the large "CALL" button firmly.
2. The button will transmit a wireless signal to the paired receiver.
3. The receiver will then activate its alert mechanism (e.g., sound, vibration, light) to notify the caregiver.

Ensure the button is within the effective transmission range of the receiver for reliable operation. Obstacles such as thick walls or electronic interference can reduce the effective range.

5. Maintenance

5.1 Battery Replacement

When the call button's signal weakens or if it stops responding, it may be time to replace the batteries. Follow the battery installation steps in Section 3.1.

• Use only CR2 type batteries.
• Dispose of old batteries responsibly according to local regulations.

5.2 Cleaning

To clean the E57 call button, wipe it with a soft, slightly damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the device's surface or internal components.

5.3 Water Resistance

The E57 is IP55 rated, meaning it is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in environments where it might be exposed to splashes, such as a bathroom. However, it is not designed for submersion in water.

6. Troubleshooting

• Button not responding:
  • Check the batteries. Replace them if necessary.
  • Ensure the button is within range of the receiver.
• Receiver not receiving signal:
  • Verify that the E57 button is properly paired with the receiver (refer to Section 3.2 and your receiver's manual).
  • Check the distance between the button and the receiver. Move them closer if possible.
  • Ensure there are no significant obstructions (e.g., thick concrete walls, large metal objects) between the button and the receiver.
  • Check if the receiver is powered on and functioning correctly.
• Interference:
  • If experiencing intermittent signals, try relocating the receiver or the button to avoid potential sources of wireless interference (e.g., Wi-Fi routers, cordless phones, microwaves).

For persistent issues, consult the user manual of your specific SINGCALL receiver or contact SINGCALL customer support.
