1011Pairing to hearing instrumentsNote! The following information is intended primarily for your hear-ing care professional, who in most cases will complete the tasks that  are  necessary  before  the  ReSound  Unite  Phone  Clip  can be used with your hearing instruments. However, the process is  designed  to  be  simple  and  should  be  easily  accomplished  by  almost anyone.1.  Make sure ReSound Unite Phone Clip is turned on. Your hear-ing instruments must be off – open the battery door.2.  With the tip of a pen or similar object, press the small pairing button on the back of your ReSound Unite Phone Clip device hidden by the bottom cover (see picture below). Press shortly until the LED indicator turns to solid blue. Your ReSound Unite Phone Clip will remain in pairing mode for 30 seconds.Getting StartedCharging the BatteryBefore using your ReSound Unite Phone  Clip,  you  need  to  fully charge the rechargeable battery. To  charge  it,  plug  the  charging cable as shown in the picture be-low.  Then  plug  the  other  end  of the  charging  cable  into  a  power outlet.During the charging process, the LED indicator will show a solid red light. A solid green light will indi-cate the fully charged status.Charging  an  empty  battery  typi-cally  takes  about  3  hours.  It  is safe to leave the charger connected overnight – the battery can-not be overcharged.•  When charging your ReSound Unite Phone Clip for the rsttime, leave it to charge for at least 3 hours, even if the battery indicator turns into a solid green light earlier.•  For safety reasons, recharge the battery only with chargerssupplied by ReSound.
1213Bluetooth PairingIf  your  mobile  phone  is  Bluetooth-enabled  and  supports  the  appropriate profiles, it can communicate with the ReSound Unite Phone Clip only after completing two simple procedures: pairing and connecting.The  pairing  procedure  allows  you  to  control  which  Bluetooth  devices are permitted to communicate with each other. It needs to be completed only once for each device you wish to use with your ReSound Unite Phone Clip.You can pair up to 8 Bluetooth devices with the Phone Clip, but only 1 Bluetooth device can be connected at a time.The pairing procedure is described in the section which follows.Once  a  mobile  phone  is  permitted  to  communicate  with  the  ReSound Unite Phone Clip by the pairing procedure, the connec-tion procedure configures the device to actually output its audio signal over the Bluetooth connection. This procedure is also de-scribed in the section which follows.Pairing to mobile phoneThe  pairing  procedure  is  controlled  by  your  mobile  phone.  Different  mobile  phones  have  different  menu  structures.  You should  therefore  refer  to  your  mobile  phone’s  manual  if  you cannot  complete  the  pairing  procedure  with  the  generic  steps  described here.3.  While  pairing  mode  is  activated,  close  the  battery  doors  of both hearing aids and make sure they are ON. A successful pairing will be indicated by an audible melody played in both hearing  aids.  You  are  now  ready  to use the ReSound Unite Phone Clip! ON and OFFTo turn ON your ReSound Unite Phone Clip, press and hold the multifunctional button (5 on page 9) for about 1 second until you see the LED indicator displaying a solid blue light. The blue light will be on for 4 seconds.To turn it OFF, press and hold the multifunctional button for about 3 seconds until the LED indicator flashes quickly 4 times and then goes dark.

Press and hold the multifunctional button on the Phone Clip for 7 seconds. The LED will now be solid blue for two minutes indicating that Bluetooth pairing mode is active. The ReSound Unite Phone Clip will be in Bluetooth pairing mode only in the first two minutes after having been turned ON.2.  Find  the  connectivity  settings  of  your  phone.  Look  for  the “Bluetooth” feature in the main menu or one of the submenus, such as “Connectivity”.3.  On  your  mobile  phone,  ensure  that  the  Bluetooth  is  turned ON.4.  On the mobile phone choose to search for Bluetooth devices.5.  Your mobile phone should present a list of Bluetooth devices discovered. Select “Hearing Aid Phone” from this list.6.  Your mobile phone may then ask you to enter a passcode. If so, enter “0000” (four zeros).Your ReSound Unite Phone  Clip should  now  be paired  to your mobile  phone.  Some  mobile  phones  may  ask  which  Bluetooth service you wish to enable. enable, select “Headset”.ConnectingOnce  your  mobile  phone  and  ReSound  Unite  Phone  Clip  are paired,  the  mobile  phone  needs  to  be  connected  before  it  will actually send the appropriate audio signals.This function should also appear in your mobile phone’s “Blue-tooth” menu, usually under a list of “Paired Devices”. In that list, highlight your ReSound Unite Phone Clip and select “Connect”. • WhenyourReSoundUnitePhoneClipandmobilephoneareconnected, you may see a headset symbol on the main screen of your mobile phone, similar to this:  The connection between the ReSound Unite Phone Clip and the mobile phone will be maintained for as long as both devices are turned ON and remain within range of each other. If either device is switched OFF or moves out of range, you may have to perform the connection procedure again.On  some  phone  you  can  configure  “Automatic  Reconnection”. We recommend that you do so if the feature is available. Refer to the user guide of your mobile phone for instructions on how to do this if supported.

2223Second,  the  range  of  possible  applications  on  a  Bluetooth- enabled  device is  defined by “profiles”. The device  you wish to  use  with  your  ReSound  Unite  Phone  Clip  must  support  the  appropriate Bluetooth profiles.To receive or place phone calls your mobile phone must support either the “handsfree” or the “headset” profile. Many, but not all  mobile  phones  support  these  Bluetooth  profiles.  Look  for  this  information in your mobile phone user guide.Bluetooth Operating RangeIn  free air, your  ReSound  Unite Phone Clip  supports  Bluetooth operation  up  to  a  range  of  approximately  10  meters.  Line-of-sight between the devices is not required. However, the following  factors may affect the maximum range:• Interferenceintheenvironment• Themobilephonewhichyouareconnectingtomaysupporta  more  limited  range  than  the  10  meters  supported  by  the  ReSound Unite Phone ClipIf  your  mobile  phone  moves  out  of  range,  the  connection  will  be terminated. If the device is then moved again within the range, the ReSound Unite Phone Clip will attempt to re-establish con-nection. Whether it achieves to do so will depend on delay since the link was broken and on the mobile phone properties.Introduction to BluetoothWhat is Bluetooth?Bluetooth provides a way for devices like mobile phones to com-municate wirelessly.First, check whether the phone you wish to use offers Bluetooth connectivity.
