NOAHlink Users Manual156 Installing NOAHlinkWhen installing your NOAHlink, you can use either rechargeable oralkaline batteries. This section describes:§ the procedure to use for each battery typeNOTE: It is recommended that you keep alkaline batteriesavailable when using your NOAHlink in case youforget to recharge your rechargeable battery and itruns down during a patient session.§ the installation procedureIMPORTANT: Your PC must have a Bluetooth device installedbefore you can begin installing NOAHlink. (Youcan check this by clicking Start on your desktop,then Settings and Control Panel. Double-click onSystem and locate your Bluetooth device.)6.1 Battery UsageNOAHlink is powered by battery – rechargeable or alkaline. Thebattery is placed in the compartment at the bottom of the unit, asillustrated below:Figure 3: NOAHlink and Battery Lid
NOAHlink Users Manual166.1.1 Alkaline BatterySimply open the battery compartment of your NOAHlink unit andplace one alkaline AA (R6) 1.5V battery inside in the correctposition by matching the symbols on the battery to those onNOAHlink.6.1.2 Rechargeable BatteryThe rechargeable battery is a 1.2V 1800 mAh NiMH battery.IMPORTANT: You will first need to charge the rechargeablebattery (described below). This takesapproximately 13 hours. Thus, you will need tocharge the battery overnight before you can installNOAHlink.Figure 4: NOAHlink, Charger Cradle and Power AdaptorThe following describes how to charge your rechargeable battery:§ Open the battery compartment of your NOAHlink unit. Placethe rechargeable battery in your unit in the correct directionby matching the symbols on the battery to those onNOAHlink.§ Place your NOAHlink in its charger cradle, matching thefront of the cradle to the front of your NOAHlink.§ Attach the charger cradle to the power adaptor and plug thisinto a socket. Your battery automatically begins to chargeand a green light is displayed. This procedure takesapproximately 13 hours.
NOAHlink Users Manual176.2 InstallationFollow the procedure below to install your NOAHlink:§ Remove NOAHlink from its charger cradle (if you haveplaced it there while charging the rechargeable battery)§ Place your NOAHlink unit not more than five meters fromyour PC in order to ensure adequate wirelesscommunication.§ Turn on your NOAHlink.§ Turn on your PC.§ An installation CD is provided with your NOAHlink. Putthis into your disk drive. If the program does not beginrunning straightaway, locate the Setup program under theFile menu and double-click on this option. The program willthen install a NOAHlink driver which connects the fittingmodule running under NOAH to the Bluetooth devicecommunicating with your NOAHlink.NOTE: If you have more than one NOAHlink unit, it isrecommended that you attach one of the name labels thatare included in your NOAHlink package to the back ofyour NOAHlink and write a suitable name on this label,for example, the location of the NOAHlink or the name ofits user. This allows you to differentiate between differentNOAHlinks. Refer to Section 7.1.1 for details on namingyour NOAHlink via your PC.
NOAHlink Users Manual187 Using and Charging NOAHlink7.1 Using NOAHlinkThe following procedure describes how to use your NOAHlink toprogram a hearing instrument:WARNING: Always remove NOAHlink from its charger cradlebefore you begin to program a hearing instrument, asthe unit switches off automatically when placed inthe charger.Always keep the charger cradle away from thepatient area.Figure 5: Using NOAHlink to program Hearing Instruments
NOAHlink Users Manual19§ Switch on your NOAHlink by pressing the button at thefront of the unit. A self-test occurs every time you do this.The following table explains the different LED (light-emitting diode) displays that may occur during the self-test,depending on the power status of the battery: POWER STATUS LED DISPLAYOK Continuous green light forfive secondsLow (battery low) Flashing yellow/orange lightfor five secondsError Flashing red light for 30seconds, then NOAHlinkpowers offOnce the self-test has been completed, your NOAHlink willdisplay different LEDs depending on:1. the power status2. whether the unit is communicating with your PCThe following table outlines the different possibilities:COMMUNICATINGWITH PC POWERSTATUS LED DISPLAYOK Quickly flashing greenlightYes Low (batterylow) Quickly flashingyellow/orange lightOK Flashing green lightevery three secondsNo Low (batterylow) Flashing yellow/orangelight every three seconds
NOAHlink Users Manual20§ Attach the cable/s (recommended by the hearing instrumentmanufacturers) for the programmable hearing instrument/s tothe connector/s at the top of the NOAHlink unit.§ Connect the ends of the neck string to the attachment pointsof your NOAHlink according to the color of their plasticconnections (red and blue). Hang the NOAHlink from theneck of your patient with this string.OR:Attach one plastic attachment button of the neck string toyour NOAHlink.
