SC01 and SC02 are dedicated expansion speakers for TM-981 PoC mobile radio, with identical physical appearance—they are indistinguishable in shape, size, color and interface. However, their functional positioning and application scenarios differ significantly, catering to different user needs for mobile radio audio expansion and communication upgrades.

SC01: Basic Expansion Speaker for Simple Audio Needs

When inserted into TM-981 mobile radio, SC01 functions solely as a reliable external expansion speaker. It enhances the device’s audio output, ideal for noisy environments or group listening, ensuring clear sound transmission. Without additional functional modules, it is a cost-effective mobile radio accessory for users who only need basic audio enhancement.

SC01 features high stability and low failure rates, requiring no complex operation-just plug and play with TM-981 mobile radio. 

SC02: Multifunctional Expansion Speaker to Unlock TM-981’s Potential

Unlike SC01, SC02 serves as a high-performance expansion speaker while unlocking advanced functions for TM-981 mobile radio, greatly expanding its application scope. It is essential for users seeking higher communication efficiency and functional diversity from their two-way radio system.

Key Extended Functions of SC02  

Repeater Function

SC02 acts as a communication repeater, bridging nearby analog radios and the distance PoC radios. It converts and forwards signals between the two, enabling seamless communication in scenarios like construction sites, outdoor operations and emergency rescue, etc.

Direct Analog Radio Communication

SC02 allows TM-981 mobile radio to directly communicate with nearby paired analog radios without intermediate devices, simplifying communication and reducing equipment costs, suitable for small-scale on-site collaboration.

Customizable Functions

SC02 supports personalized function development. Our professional R&D team can tailor functions to meet specific user requirements for TM-981 mobile radio expansion.

In summary, SC01 is a basic external speaker designed for simple audio needs, making it ideal for budget-conscious users. SC02, by contrast, is a multifunctional upgrade that enhances audio output and unlocks extended communication capabilities. The choice depends on user needs, scenarios and budget: SC01 for simplicity and cost efficiency, SC02 for enhanced communication efficiency and advanced mobile radio functionality.
