Operation Manual 1. INTRODUCTION 1.1. About This Manual The main purpose of this manual is to provide information to ensure the optimum use and performance of the EQ Link and EQ Reverse Link Wireless Communications system. It also provides advanced information for users who require extra functions other than those supplied “out of the box”. 1.2.
Operation Manual 2. FUNCTIONAL OVERVIEW Thank You for purchasing the EQ Link and EQ Reverse Link (EQ-R-Link) system. The EQ Wireless Communications system is a state of the art audio communication device specifically designed for Aviation headset applications in high noise environments. The EQ wireless system is compact; it includes re-chargeable batteries and microphone noise cancelling circuits for optimum listening pleasure. The devices feature only the essential controls to ensure ease of operation.
Operation Manual 2.1. System Features The system includes the following functionality: • Full voice prompting system for ease of user interface navigation and control. • Headset Volume and VOX controls to suit the user headset. • Microphone noise cancelling algorithms. • Auto Muting of Auxiliary audio inputs during VHF reception. • Auto VOX open on PTT for no loss of voice conversations.
Operation Manual 3. BASIC OPERATION 3.1. EQ-Link Controls The EQ-Link has a number of controls and system inputs, these are described below: Mini USB Used for charging. 3.5mm Audio User for Cell Phone/Blue Tooth or MP3 player. Status Button Used to read battery capacity, transmitted to headset. Used also to change mode from Master to Slave. Used to enter Menu Mode for advanced features. Status LED’s Green is used for charging indication and Master Indication.
Operation Manual 4. SYSTEM FUNCTIONS 4.1. EQ-Link The EQ-Link is the heart of your headset system that wirelessly connects the EQ Reverse-Link and provides the interface for your radio and communications system. The EQ-Link will power on when your aircraft’s communication system operates. Please note Pairing and other setting can be changed by plugging EQ-Link into its supplied charger but the EQ-Link must be plugged in to a powered intercom system in order for communications to operate properly. 4.2.
Operation Manual 4.3. PTT Detection The EQ-Link can detect when the aircraft PTT is activated, this is indicated by the YELLOW LED going fully on. This can aid in the detection of PTT Faults and also as a general PTT indication. On each PTT press a short tone (BEEP) will be heard in the headset and when PTT is released a short tone (BOP) will also be heard. We call these comfort tones and they give feedback that you really have pressed and released the PTT button in the aircraft.
Operation Manual 4.5. EQ-Link Communications Settings The EQ-Link will function at peak performance when the aircrafts communications settings can be adjusted to suit. The EQ-Link acts as a cable replacement for standard Headsets and as such will receive any imperfections in the aircraft communications system. Advanced features can be activated on the EQ-Link to further assist the noise reduction performance of the system. These modes are activated by 3 fast clicks of the STATUS button on the EQLink.
Operation Manual Standard EQ Link Modes include: Microphone noise cancelling DSP algorithms. This mode will process the audio from the headset microphone and provide additional filtering and processing to reduce noise induced into the headset microphone and can be very useful for noisy aircraft situations.
Operation Manual 5. INSTALLATION 5.1. Installation EQ-Link system The EQ-Link system is supplied with a standard aviation cables and connectors (jacks) to suit standard aviation connections. The EQ-Link system will automatically power ON when the aircraft communications system is turned on, and will automatically power off when the communications is switched off. A permanent optional charge cable can be connected for peace of mind to ensure the EQ equipment is always charged.
Operation Manual 6. EQ-LINK / EQ-R-LINK CHARGING The EQ Reverse Link systems have the most advanced battery monitoring and charging system of any headset system on the market today. This ensures that your flying will be trouble free and you are able to judge the operational time of your EQ headset system correctly. The devices are fitted with the latest NiMh low loss technology. These batteries will lose approximately 1% of their stored charge per month when not in use.
Operation Manual 7. HINTS AND TIPS ON OPERATION. Make sure that the system has fully charged batteries. ( Green LED Fully ON ) Make sure the EQ-Link is not behind metal walls in the aircraft as this will limit the effective range of the system. Make sure the VHF antenna or other high powered transmitters are a least 2 meters from the headset system. If the VHF antenna is too close to the headset then Radio frequency feed back will occur in the headset when transmitting on VHF.
Operation Manual 8. VOICE MENU PROGRAMMING EQ R-LINK. 8.1. EQ Reverse-LINK The tree diagram shows how to program each of the sections of the EQ Reverse-Link.
Operation Manual Voice guides will help navigate through the menu system, if unsure the system will time out and return to normal operation after 5 seconds. If a mistake is made it can be reprogrammed. If completely lost and unsure the FACTORY RESTORE option will reset the EQ R-Link to an out of box state as delivered from the factory. Pairing will need to be performed in this case when using EQLink systems. 8.2.
Operation Manual 9. VOICE MENU PROGRAMMING THE EQ-LINK The tree diagram shows how to program each of the sections of the EQ-Link. Functions are explained below.
Operation Manual 9.1. Microphone Noise Reduction The microphone noise reduction when activated will add extra DSP processing of the signal from the headset microphone to the intercom system. This algorithm will remove constant noise signals in the background and process the voice to remove noise components. Some loss in signal richness is expected when this mode is activated. Large gains in signal to noise performance is expected when using this is very noisy aircraft. 9.2.
