What makes the s.QUAD C35 model stand out?

  • Use of a eSIM with integrated connectivity
  • Excellent reception characteristics, also in mobile radio operation
  • Up to seven days of battery life, whilst being connected permanently to the mobile phone network
  • Extremely robust, dust and waterproof

With its integrated mobile radio module, the digital pager meets the requirements of the latest technological developments in the network infrastructure and can therefore thus also be used for future-oriented IoT projects. This also enables the demand for the much sought-after remote configuration and allows firmware updates regardless of location.

Other features of the pager are excellent reception (sensitivity 2µV/m) and a configurable loud alarm, with up to 95 dB. The pager can withstand exposure to dust and splash water as well as a drop from a height of two meters. These features help prevent damage and reduce operating costs.

In power management, the proven standard AA round cell excels with its long runtime and masters an operating time of up to seven days with constant mobile network connection. In POCSAG mode, the runtime increases to several weeks.

With the LTE module, the pager enables alerting via POCSAG and mobile network technology. Feedback is therefore thus guaranteed, and an on-demand follow-up alerting ensures high efficiency and speed in alerting.


Ergonomic operation and optimal high wearing comfort ensures acceptance by the users.

Your Pager-Options

If you want to send the same alarm text to several groups or individuals, then you save valuable time with the Express Alarm®. By linking several call addresses with the alarm text, the amount of data to be sent and thus the time for sending the alarm is reduced.

GLOBE is a replace text pattern option that allows you to either suppress text or replace it with a fixed text. In an idle state, the pager is set in sleep mode with the display switched off. At all times, the pager remains active and ready to receive alarm signals.

The RSSI (Received Signal Strength Indicator) is an indicator of the quality of the received radio signal over the air. The higher this value, the better the reception at that location. The value is indicated on the unit by a bar graph. In combination with the return channel, the RSSI can be sent back to a system for quality control.

Swissphone’s IDEA™ encryption enables the secure transmission of confidential messages. All messages are encrypted (end to end) from the input to the pager and thus cannot be read by unauthorized persons.

The reception frequency can be programmed within a bandwidth of up to 10 MHz

In an idle state, the pager is set in a sleep mode with the display switched off. At all times, the pager remains active and ready to receive alarm signals.
