    Self test 3.3.1.1. Switch on the equipment. new spirotel will carry out the so-called self-test for approx 3 seconds. It is assumed that when the self-test is passed all functions of new spirotel are okay. Any severe malfunction (if any) will be reported on the display.

  • Page 12: Opening The Device

    Opening the device 4.2.1. To open new spirotel: 1. Switch off the device and make sure that the turbine housing is removed from the main body of the device. 2. Place the device on a flat surface with bottom part face-up 3.
  • Page 13 PCBs and components Removing and replacing the turbine sensor strip 4.3.1. Open new spirotel as described in 4.2.1. With the device face down, locate where the sensor strip is connected to the PCB. Using a screwdriver or case opener, carefully pry the clear plastic clip from the centre underneath.

    Removing and replacing the display 4.3.2. Open new spirotel as described in Paragraph 4.2.1; once the PCB is separated from the sensor strip (as described in 4.3.1, and removed from the yellow casing, unclip the flat cable and remove the display.
  • Page 15 Removing and replacing the internal battery pack 4.3.4. Open new spirotel as described in Paragraph 4.2.1 up to point 3. Remove the battery pack, only after the device is switched off, by withdrawing the connector using a screwdriver or a tweezers.
  • Page 16 Use only the battery charger supplied by MIR to recharge the battery pack. Recharging with an unsuitable charger in nonconforming conditions may cause the battery pack to overcharge or the charging current to be extremely high thus causing abnormal chemical reactions in the battery pack triggering acid leakage, overheating, smoke breakage an explosion and/or fire.
  • Page 17 Turn on new spirotel and setup the device to perform a spirometry test (for example FVC).  Hold the new spirotel with one hand and move it slowly sideways, having the air pass through the turbine.  If the rotor spins properly the device will emit a series of acoustic signals “beeps”. The beeping frequency is a function of the air flow passing through the turbine.
  • Page 18 To clean the reusable turbine, first remove it by pulling it gently from the new spirotel turning it anti-clockwise and pressing lightly. It can be helpful to push it gently from underneath with one finger from the bottom of the turbine to lift it out of its housing.
