# Motorsport Race Receivers

# Introduction

<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Thank you for purchasing your **Speedtech Motorsports Receiver**.  
These instructions are designed to provide **simple, easy-to-follow guidance** for setup and use. Please note that **none of the advanced features is required** for regular operation.</span>

<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Your receiver is a full two-way radio, meaning it can transmit and receive. However, on the **Motorsport channels**, the **transmit function has been disabled** to ensure compliance and prevent accidental transmissions during events.</span>

<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Before your event, make sure the radio is **fully charged**. You can charge it in one of two ways. Use the supplied charging cradle or connect a **USB cable** directly to the **USB port** located **below the speaker/microphone socket** on the side of the radio.</span>

# Channels

<span lang="en-us" style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Please ensure you select the correct channel for the Motorsport service you wish to receive using the buttons on the side of the radio below the Push to Talk button.

#### **<span style="font-family:'Century Gothic', sans-serif;">What is the Public Radio Service (PRS)?  
</span>**<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">The Public Radio Service (PRS) is a set of free-to-use UHF channels available throughout New Zealand. These channels are open to anyone and do not require a licence. By selecting a PRS channel, you can communicate directly from radio to radio without needing any additional infrastructure or registration.</span>

# Advanced Radio Functions

<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Your radio includes several advanced features that can be activated using the channel up/down keys. These functions are triggered with a long press, which means holding the button(s) for more than two seconds.</span>

**<u><span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Channel Lock</span></u><span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">  
</span>**<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">The **Channel Lock** feature prevents accidental changes to your selected channel.</span>

- - <span style="font-size:10pt;line-height:115%;font-family:'Century Gothic', sans-serif;">To **activate Channel Lock**, press and hold **both the UP and DOWN buttons** together for more than two seconds. (You will hear a single *“beep”*, indicating that the channel lock is active)</span>
    - <span style="font-size:10pt;line-height:115%;font-family:'Century Gothic', sans-serif;">To **deactivate Channel Lock**, repeat the same action. (A double *“beep”* will confirm that the channel is unlocked)</span>

**<u><span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">Monitor Function</span></u><span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">  
</span>**<span style="font-size:11pt;line-height:115%;font-family:'Century Gothic', sans-serif;">The **Monitor Function** temporarily disables the **squelch,** a feature that blocks background static or weak signals when no transmission is detected.</span>

- <span style="font-size:10pt;line-height:115%;font-family:'Century Gothic', sans-serif;">To **enable monitoring**, press and hold the **UP (+)** key.</span>
    - <span style="font-size:10pt;line-height:115%;font-family:'Century Gothic', sans-serif;">This will allow you to hear all signals, including weak ones that wouldn’t normally pass the squelch filter.</span>
- <span style="font-size:10pt;line-height:115%;font-family:'Century Gothic', sans-serif;">To **disable monitoring**, release the button.
