The R21 Telephone Dialer Stored Phone Numbers can store up to how many numbers?

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

Answer: (B)

The main idea here is how many contacts you can store for quick dialing on the R21 Telephone Dialer. This device uses memory slots to hold individual phone numbers you常 call often, so you can speed-dial without manually entering digits each time. The built-in capacity is one hundred entries, which gives a solid pool of frequently contacted numbers and makes field communications faster. Each stored entry can usually be labeled for easy identification, so you know which number you’re dialing at a glance. If you ever need more than that, you’d manage space by deleting or overwriting older entries to free up slots. The other options describe smaller or larger capacities that don’t match this dialer’s actual design, making one hundred the correct, practical limit.
