Smaller than the large-size "red phone," a newly redesigned red telephone is introduced in November 1971. The receiver hook on top of the phone is 5 centimeters lower than on its larger predecessor, making the new model easier to install in storefront locations. Obstructions created by improper insertion of coins and foreign objects can also be cleared easily by pressing the hook button. By notifying the store owner, callers can also access special service numbers 110, 119, 104, 105 and 100.
