Training may be needed for Calibration and Testing to make sure that the child can recognize the animal pictures and their voices.
Some children - especially living in the big cities - may not be familiar with the animal pictures and their voices.
During training sounds are played much louder than during the test. Train the child to correlate these sounds with the animal pictures correctly and in repetitive manner. You can use Speaker, L or R Earphones, but the easier way is to use Speaker and move the mb.phone from side to side and even bring it closer to the ear if needed.
You can play these sounds many times for all 3 animals to achieve positive training results.

During the Training you can select and play the animal voices unlimited times. After you finish training select Back ( top right corner above the cow picture ) to go back to the Menu.

Touch the long white strip to display keyboard with letters. Type the correct letters of the User Id. Select the numbers’ icon in the left bottom corner to display keyboard with the numbers. Type the correct numbers of the User Id and select OK. The pictures of 3 animals and calibration scale will appear on the screen.
Note: it will not be possible to make a new or correct existing Calibration, if the User Id is incorrectly entered. This is to protect the Calibration status against the unauthorized persons - especially children.

Before you start Calibration make sure that the child is familiar with the animal pictures and voices. If not go to Training first.
Calibration establishes the settings for future testing, based on the minimal volume for each testing sound, being just sufficient for the child with recently proven normal hearing ( free of cold, infection, wax build up etc. ) to correctly recognize each sound and correlate it with the animal picture in a repetitive manner.
Volume level can be controlled using the buttons - , + or slider on the scale. The scale position is numbered.
If you use Earphones each earphone has to be calibrated separately. If you use Speaker play these voices from the distance of about 30 cm at the child’s ear level from the mb. phone and use about the some distance later during the hearing tests. This is not very critical during the test, because even 50% change in this distance will reduce or increase the volume of the sound by only about 6dB.
After calibration is done for all 3 sounds select Back ( top right corner above the cow picture ) and you will return to the Calibration Menu to choose another Earphone or Speaker. When finished Calibration procedure select Back to Menu.
Calibration will be saved, even if the mobile phone is later turned “off “ and switched “on” again. It is advisable to keep a separate record of the calibration numbers for each source of sound ( Speaker, L and R Earphones ) and each type of the testing sounds.
