The R21 Dialer can store up to how many phone numbers?

• A. 50 numbers
• B. 100 numbers
• C. 200 numbers
• D. 500 numbers

Answer: (B)

The key idea here is the dialer’s fixed storage for quick-dial numbers. The R21 Dialer is designed to hold a finite list of phone numbers you can dial without typing each time, and its documented maximum is one hundred numbers. This provides a practical balance: enough entries to cover commonly used contacts or lines while keeping memory use reasonable for the device. If you needed fewer numbers, you could store fewer, but the limit reflects the device’s capability. Larger limits like two hundred or five hundred would exceed what the hardware typically supports, so they aren’t applicable.
